Early colorectal cancer (ECC) is defined as T1NXM0 colorectal cancer (CRC). Although a non-negligible number of T1-CRCs presents metastatic lymph-nodes, local excision is increasingly proposed as alternative to radical resection. Several criteria have been suggested to identify low-risk T1-CRC, but recommendations on this topic are still heterogeneous. This study aims to identify criteria associated with N+ T1-CRC, to select patients to undergo (or not) local excision.A retrospective analysis of demographic, clinical, and histology criteria of 122 consecutive T1-CRC patients undergoing radical resection at Parma University Hospital between 2000 and 2018 has been performed.Lymph-node metastasis (LNM) was observed in 15/122 patients (12.3%). No LNM was observed among well-differentiated (G1) tumors (0/37), while 10/65 (15.4%) G2 cases as well as 5/20 (25%) G3 patients presented LNM. G1 was associated with absence of LNM (p = 0.013). After excluding G1 patients, the rate of N + T1-CRC was 17.6% (15/85). LNM was observed in 4/8 (50%) patients with lymphovascular invasion (LVI) and in 11/77 (14.2%) without LVI. LVI resulted being associated with LNM (p 0.042). LNM was reported in 28.3% of cases with a tumor infiltration 4.25 mm (13/46), compared to 5.1% in cases with an infiltration ≤4.25 mm (2/39) (p = 0.012). In Cox regression analysis, the higher hazard ratio (HR) was reported for the LVI + and infiltration 4.25 mm (HR 24.849).In patients with ECC (pT1NXM0), good differentiation (G1), absence of lymphovascular invasion (LVI-), and tumor radial infiltration ≤4.25 mm may allow performing local resection and avoiding radical surgery.

Malignant pleural mesothelioma (MPM) is an asbestos‐related and locally invasive tumor with poor prognosis. The acquisition of histological material is mandatory in order to establish a diagnosis. In this situation, the sampling of tissue is generally performed via a thoracoscopic pleural biopsy, either medically or surgically. The use of endobronchial ultrasound‐guided transbronchial needle aspiration (EBUS‐TBNA) or transesophageal fine needle aspiration with an EBUS scope (EUS‐B‐FNA) of pleural lesions have only rarely been reported due to the theoretical limitations of tissue acquisition in such cases. We herein report a rare case of MPM successfully diagnosed via EUS‐B‐FNA in a 49‐year‐old woman with an unusual presentation characterized by solid thickening in the right mediastinal pleura., We present a rare case of MPM successfully diagnosed via EUS‐B‐FNA. The use of EUS‐B‐FNA and EBUS‐TBNA for pleural sampling is unusual because the standard approach to pleuropathy is a pleural effusion analysis followed by thoracoscopy or image‐guided pleural biopsy. However, when one or more pleural lesions are near to the central airway or esophagus, EUS‐B FNA and/or EBUS‐TBNA should be considered and one of them chosen because of their simplicity and safety.

Simple Summary Vulvar squamous cell carcinoma (VSCC) is the most frequent malignant vulvar tumor, with a peak incidence in the 7–8th decades of life. However, VSCCs can also occur in young women. This unfortunate event is even rarer and more worrisome in pregnant women, being hard to manage for gynecologists, oncologists, and radiotherapists. Very few cases have been reported and we felt the need for an updated review on this topic. Thus, we performed a systematic literature review of VSCCs diagnosed during pregnancy, discussing the clinic-pathologic features, the implications in pregnancy outcomes, and the effects of such a diagnosis in the management of mothers and their babies. Abstract According to our systematic literature review (PRISMA guidelines), only 37 vulvar squamous cell carcinomas (VSCCs) were diagnosed during pregnancy (age range: 17–41 years). The tumor size range was 0.3–15 cm. The treatment was performed after (14/37, 38%), before (10/37, 27%), or before-and-after delivery (11/37, 30%). We found that 21/37 (57%) cases were stage I, 2 II (5%), 11 III (30%), and 3 IVB (8%). HPV-related features (condylomas/warts; HPV infection; high-grade squamous intraepithelial lesion) were reported in 11/37 (30%) cases. We also found that 9/37 (24%) patients had inflammatory conditions (lichen sclerosus/planus, psoriasis, chronic dermatitis). The time-to-recurrence/progression (12/37, 32%) ranged from 0 to 36 (mean 9) months. Eight women died of disease (22%) 2.5–48 months after diagnosis, 2 (5%) were alive with disease, and 23 (62%) were disease-free at the end of follow-up. Pregnant patients must be followed-up. Even if they are small, newly arising vulvar lesions should be biopsied, especially in women with risk factors (HPV, dermatosis, etc.). The treatment of VSCCs diagnosed in late third trimester might be delayed until postpartum. Elective cesarean section may prevent vulvar wound dehiscence. In the few reported cases, pregnancy/fetal outcomes seemed to not be affected by invasive treatments during pregnancy. However, clinicians must be careful; larger cohorts should define the best treatment. Definite guidelines are lacking, so a multidisciplinary approach and discussion with patients are mandatory.

Cribiform-morular thyroid carcinoma is a rare variant of papillary thyroid carcinoma. It is usually related to Familial Adenomatous Polyposis (FAP) but rarely it may be sporadic. This variant of PTC occurs in young females and it is rare in the elderly. We report a case of a 20-year-old female presenting thyroid carcinoma and personal history of FAP. (www.actabiomedica.it)

A 79-year-old woman presented with a long history of peripheral eosinophilia. Previous right hemicolectomy for colonic polyposis was reported. Laboratory tests were notable for mild macrocitic anaemia and eosinophilia. β2 microglobulin and serum tryptase levels were elevated. Serum immunofixation revealed IgA/kappa monoclonal protein. Bence-Jones protein was positive. Bone marrow (BM) biopsy revealed the coexistence of two neoplastic components. Cohesive clusters of bland-looking, spindle-shaped mast cells, representing 20% of marrow cellularity, were close to aggregates of mature plasma cells occupying 40% of marrow cellularity. Molecular analysis on marrow aspirate demonstrated KIT D816V mutation, TET2 mutation, monoallelic deletion of TP53/17p13 and trisomy of ATM/11q23. A bone density study revealed mild osteoporosis. Full skeletal X-rays and magnetic resonance imaging (MRI) of spine and hips showed multiple, small rarefaction areas and an old L1-L2 fracture, both ascribed to osteoporosis. The association of systemic mastocytosis (SM) and multiple myeloma (MM) is very uncommon. The coexistence of SM with MM placed our patient in the SM with associated clonal haematological non-mast-cell lineage disease (SM-AHN) subtype. Midostaurin therapy was started.
