Background Diabetes mellitus (DM) is a chronic disease characterized by elevated blood glucose levels that can lead to serious complications. Nails are a mirror for general health so changes in nails can be an indicator of disease progression in patients with DM. Aim To detect subclinical nail changes in patients with DM using dermoscopy. Methods In total, 100 participants were recruited, all of them from outpatient clinics, made up of a group with DM (n = 50) and an age- and sex-matched control group without DM (n = 50). All patients had clinically apparently normal nails. In both groups, dermoscopic examinations were conducted and compared. Results It was found that 33 patients in the DM group (66%) had dermoscopic nail findings in the form of microhaemorrhage (26%), longitudinal striations (24%), distal subungual onychomycosis (24%), superficial pitting (20%), distal onycholysis (18%), splinter haemorrhage (14%), subungual hyperkeratosis (12%), dilated vessels (10%) and distal yellowish discoloration (8%). Conclusion Nail examination can be accomplished with the help of dermoscopy to detect subclinical nail changes in patients diagnosed with DM and, therefore, can give us an idea about disease progression and help with control of DM and treatment plans.

The new coronavirus COVID-19 pandemic has had an unprecedented impact on global health and economic growth. A widely used vaccine is the weakened inactivated severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2) virus (Sinopharm). Following major SARS-CoV-2 vaccination campaigns, cutaneous symptoms are on the rise.This study is a prospective observational study evaluating cutaneous reactions and time of recovery after Sinopharm vaccination. The cases involved were over the age of 18. The data were anonymized. On the registry's vaccine section, we tracked vaccination dates, skin reactions, and recovery times. All respondents who reported only a cutaneous reaction to the first vaccination dose received a follow-up contact asking about a second vaccination dose cutaneous reaction.The study included 4560 cases. The mean age of all studied cases was 41.2 ± 6.1 years. There were dermatologic complications in 1190 patients (26.1%). There was induration at the injection site in 495 patients (10.9%), urticaria in 210 patients (4.6%), morbilliform eruption in 375 patients (8.2%), flare of skin site in 105 patients (2.3%), and angioedema in 105 patients (2.3%). The mean recovery days in all studied patients were 2.92 ± 0.94 days with a minimum recovery period of 2 days and a maximum of 7 days.Because Sinopharm's cutaneous reactions are frequently mild and self-limiting, vaccination should not be discouraged based on these findings. If the first vaccine dose creates a cutaneous reaction, there is no need to skip the second dose.

Background Some basal cell carcinoma (BCC) patients are considered as a high risk regarding the site, size, histopathological variant, or recurrence. High-risk BCC is a challenging therapeutic problem due to the trial to balance between complete surgical excision from one side and tissue preservation from the other side. Aim To evaluate the efficacy of combining ablative CO2 laser, imiquimod 5%, and diclofenac 3% as a therapeutic regimen in high-risk and inoperable BCC. Patients/methods The study was conducted on 14 patients that were assessed clinically and pathologically then categorized regarding the site, size, histopathology, and fitness for surgery as high-risk inoperable BCC. They received an ablative session of CO2 laser, followed by application of diclofenac sodium 3% gel once daily for 5 days and imiquimod 5% cream for another 2 days. Results The study included 11 males and 3 females. Nine lesions were located on the scalp, 4 on the face, and one lesion on the trunk. All lesions were of large size >5 cm in diameter. Histopathology showed 4 patterns: nodular type in 8 patients, infiltrating type in 3 patients, metatypical type in 2 patients, and micronodular type in one patient. At the end of the treatment period, 9 patients showed significant (moderate to marked) improvement while 5 patients showed weak (poor to mild) response. Significant improvement was more observed in nodular type. Relapse was more observed during the 5th to 6th months with 2 patients showed no relapse. Conclusion This combined regimen is a good alternative therapeutic modality in high-risk inoperable BCC especially the nodular pathologic pattern.

Vitiligo is a skin disorder in which the melanocytes are destroyed. Melanocytes can be destroyed anywhere in the body, compromising the function of the organs where they are found. Melanocytes in the epidermis and the uveal tract share a common embryological origin in addition to physiological and morphological similarities. Our aim was to detect ocular changes in non-segmental vitiligo patients.This study included 40 non-segmental vitiligo patients and 40 healthy volunteers as a control. Visual acuity testing, slit lamp examination and optical coherence tomography were performed on all patients as well as controls.Patients with non-segmental vitiligo had a considerably greater incidence of ocular alterations than controls, although there was no significant difference in visual acuity.Vitiligo is a systemic condition that can affect the activity of melanocytes in organs besides the skin. The depigmentation process can influence ocular melanocytes. Ocular problems may be closely connected to vitiligo. Because ocular melanocytes aren't involved in the detection or transmission of visual pathway, there is no vision impairment.

Androgenic alopecia (AGA) is a common condition associated with loss of terminal hair on the scalp in a specific pattern in both males and females. Management of AGA is usually challenging as the approved therapeutic options are limited. Our aim was to evaluate the efficacy of non-enzymatic stromal vascular fraction (SVF) as a new promising treatment for AGA. From April to December 2021, this prospective study included 30 patients with AGA who were enrolled from the University Hospitals' dermatology outpatient clinics. Patients received a single session of autologous SVF injection and were then followed up for 6 months. There was an increase in hair shaft caliber from 0.037 ± 0.01 mm before treatment with SVF to 0.056 ± 0.02 mm after 6 months of treatment. Also, hair count/cm2 increased from 130.87 ± 14/cm2 to 151.93 ± 22.36/cm2 and terminal to vellus hair ratio increased from 77.06 ± 10.47% to 81.45 ± 11.98% at the end of the study. No significant difference was recorded between male and female groups as regard response to treatment. We concluded that SVF is an effective line of treatment for AGA with significant improvement regarding hair density, hair diameter, global photography, and patient satisfaction.

Purpose Basal cell carcinoma (BCC) is the most diagnosed type of cancer accounting for 80% of all keratinocyte malignancies. However, the exact demographic properties and clinicopathological criteria for BCC in Egyptians are not clearly reported. Our aim is to report and analyze the epidemiological and clinicopathological features of BCC in Egyptians. Methods We retrospectively reviewed the medical records for patients diagnosed pathologically with BCC during the period from January 2017 to December 2021. Data were recruited from four dermatology centers with different geographical distributions. Results We registered 544 patients. Their age ranged between 22–91 years with a mean of 61.6 ± 13.2 years. Females showed younger age of onset. The mean duration of the tumor was 3.9 ± 3.8 years. The most common involved region was the head (79.4%), and about one third of patients (32.2%) had a giant lesion (> 5 cm). The most common clinical presentation was ulcerative lesions (44.9%). Pathologically, the nodular type represented the most common variant (50.4%). Conclusion Our results proposed that the annual incidence of BCC is increasing among Egyptians. Ultraviolet radiation is considered a high-risk factor of BCC leading to a higher affection of the head region and more prevalence in men. This study also highlights some criteria of BCC in Egyptians such as the long duration of the tumor, the early onset in females, the higher percentage of giant types, and the predominance of nodular type. To our knowledge, this is the first report describing the characteristic features of BCC among Egyptians.

Spotted grouped pigmented nevus is a distinct form of non-giant congenital melanocytic nevi. Histopathologically, it tends to proliferate around the skin appendages. We report a case of a 10-year-old boy with clinical and pathological findings consistent with the diagnosis of spotted grouped pigmented nevus of more than 20 cm diameter, which is considered giant.

Granular cell tumors (GCTs) are rare soft tissue tumors of Schwann cell origin that manifest as papulonodular lesions and occur mainly in adults. The diagnosis is usually confirmed by histopathology. Most of GCTs are benign, but some lesions may exhibit malignant criteria. This study is a retrospective case series including all children with histopathologically documented multiple GCTs who attended the dermatology department of the university hospitals between February 2008 and March 2021. The objective of our study was to raise awareness to this unrecognized and rare entity in such age group. The study included 9 patients (6 girls and 3 boys) with multiple GCTs. Their age ranged between 5 and 13 years. The lesions were skin-colored to light brown, firm, smooth-surfaced nodules. Most of the lesions were on the extremities, and their mean diameter was 160.5 mm2. None of the lesions exhibited any malignant criteria on histopathology. No extracutaneous or mucosal lesions were detected. Dermatologists should be aware of this rare condition in children because early recognition allows more conservative resection of the tumor and less invasive reconstruction of the defect. Our study highlights that multifocality does not necessarily indicate malignancy or other systemic comorbidities.

Pediculosis capitis is a common condition caused by infestation with the human head louse, Pediculus humanus capitis, and primarily affects children in the age-group of 6–12 years. The most prominent symptom is intense scalp itching, yet moving lice or nonmoving nits may be seen on the scalp and hair. Tinea capitis, also known as scalp ringworm, is a superficial fungal infection caused by keratinophilic fungi termed dermatophytes. Tinea capitis is rare in adults, and its symptoms include hair loss, dry scaly areas, redness, and itching. We here report a case of a rare coexistence between pediculosis capitis and tinea capitis in an otherwise healthy adult female, motivating the search for a possible cause of this rare coexistence and alarming dermatologists to be aware of the modified clinical appearance of this coexistence which could be mistaken with other conditions such as cutaneous lupus erythematosus or lichen planopilaris.

Background: Scars are the common and unpleasing result that occur following injuries of different causes. They have a great impact on the affected subjects both physically and psychologically. Aim: The aim of this study was to evaluate the role of autologous nanofat injection in refining the esthetic appearance of post-traumatic scars, along with pathological correlation of the results. Patients and methods: Nineteen patients with post-traumatic scars were treated with a single session of nanofat injection. The results were assessed after 6 months from the session using Vancouver scar scale (VSS) in addition to pathological evaluation via image analyzing system. Results: The age ranged between 19 and 40 years old. Statistical significant improvement on the VSS was noted regarding the height and pigmentation of the treated scars. On histopathological evaluation, there was a high statistical significant increase regarding epidermal thickness, collagen fibers, elastic fibers, and vascularity. Conclusion: Nanofat injection is a potential efficient therapeutic modality for post-traumatic scars.

Background Scars are the unfortunate outcome of most injuries and some diseases. Its psychological impact on patients can deeply affect their quality of life. Aim The aim of this study was to evaluate the efficacy of autologous nanofat injection in improving the aesthetic outcome of scars, combined with histopathological correlation of the response. Patients and methods Thirty patients with scars of different etiologies undergone one session of nanofat injection and evaluation was done 6 months after the session. Efficacy of treatment was assessed clinically using Vancouver scar scale by two independent blinded dermatologists and histopathologically using image analysis system. Results The age of enrolled patients ranged from 18 to 40 years old. There was a statistically significant improvement on the total Vancouver scar scale regarding the height and pliability of the scars. Pathological evaluation showed an increase in epidermal thickness, increased number and density of collagen and elastic fibers along with neovascularization. Conclusion Evidenced by clinical and pathological improvement, autologous nanofat injection is an effective strategy for treating scars of different etiologies.
