Background Patients with Stevens-Johnson syndrome (SJS)/toxic epidermal necrolysis (TEN) have high mortality rates. Disseminated intravascular coagulation has been reported in SJS/TEN patients. The influence of this lethal complication in patients with SJS/TEN is not well known. Objective This study aimed to investigate the risk and outcomes of disseminated intravascular coagulation in patients with SJS/TEN. Methods We analyzed the disseminated intravascular coagulation profiles of patients receiving a diagnosis of SJS/TEN between 2010 and 2019. Results We analyzed 150 patients with SJS/TEN (75 with SJS, 22 with overlapping SJS/TEN, and 53 with TEN) and their complete disseminated intravascular coagulation profiles. Disseminated intravascular coagulation was diagnosed in 32 patients (21.3%), primarily those with TEN. It was significantly associated with systemic complications, including gastrointestinal bleeding, respiratory failure, renal failure, liver failure, infection, and bacteremia. Additionally, SJS/TEN patients with disseminated intravascular coagulation had elevated procalcitonin levels. Among patients with SJS/TEN, disseminated intravascular coagulation was associated with a greater than 10-fold increase in mortality (78.1% vs 7%). Limitations The study limitations include small sample size and a single hospital system. Conclusion Disseminated intravascular coagulation is a potential complication of SJS/TEN and associated with higher mortality. Early recognition and appropriate management of this critical complication are important for patients with SJS/TEN.

Cutaneous verrucous carcinoma is a rare variant of low-grade squamous cell carcinoma. It usually involves distal extremities and is often misdiagnosed as giant warts. Multiple cutaneous verrucous carcinomas are rare in the English-language literature. We describe a 41-year-old man with multiple verrucous plaques on both feet and ankles, as well as the left thigh. Immunohistochemical study with proliferating cell nuclear antigen revealed positive staining of the basal and suprabasal layers. The patient's condition was successfully treated with systemic acitretin.

Background The scalp is a unique anatomic region, in which pilosebaceous follicles are concentrated. Objective We sought to investigate demographic characteristics and histologic distributions of malignant scalp tumors. Methods Primary and metastatic scalp malignancies diagnosed histopathologically between 1983 and 2003 were reviewed. Age at diagnosis, sex, and histologic types were analyzed. Results A total of 398 Taiwanese patients (200 males, 198 females) were selected. Age at diagnosis ranged from 3 to 103 years. Most malignant scalp tumors (69.8%) occurred in those 50 years or older. Basal (41.2%) and squamous (16.6%) cell carcinomas were the most common histologic types. Surprisingly, metastatic tumors (12.8%) came in third, in which lung cancers were the most frequent primary tumor in both male and female patients. Limitations In our series, the case number of metastatic scalp malignancies was underestimated because not all patients with metastatic scalp tumors received a scalp skin biopsy. Conclusion Because a wide spectrum of primary and metastatic malignancies can occur on the scalp, scalp inspection should be included in general screening for either skin or internal cancers.

A 58-year-old man with diabetes had fever and chills 5 days after ingestion of raw seafood. Nausea, vomiting, watery diarrhea, bilateral calf pain, and neck stiffness subsequently developed. Generalized edema and ecchymotic patches with a vesiculobullous eruption appeared on the extremities. Four blood cultures were positive for Vibrio cholerae non-01. The patient was successfully treated with antibiotics. This is the first documented case of V. cholerae non-01 septicemia with cutaneous lesions and meningitis in Taiwan.
