We report alopecic syndrome (hair loss in areas of the body, including chest, abdomen, and back) in four frugivorous bat species (Artibeus jamaicensis, Artibeus lituratus, Sturnira lilium, and Sturnira ludovici) within urban and periurban areas of Villahermosa, Tabasco, México, during 2007 and 2008. The overall prevalence of alopecic syndrome was 5.25% (135/2,567 bats). The highest prevalence was found in A. lituratus (5.6%; 62/1,105), followed by A. jamaicensis (5%; 3/1,462). We found a higher prevalence in the dry season, when more than 90% of the alopecic individuals (n=122) were captured. Higher prevalence of alopecia was recorded in urban areas (80% of captured alopecic bats, n=108) than in periurban areas (20%, n=27). Histopathologic studies revealed no evidence of infectious agents. The syndrome may be related to nutritional or endocrinal deficiencies. Spatial and seasonal aggregation in urban areas suggests that anthropogenic activities may interfere with nutritional processes. Further studies are needed to confirm the etiology of the syndrome as well as its impact on population dynamics. This is the first report of alopecic syndrome in sylvatic bats.

Background: Brooke-Spiegler syndrome is a rare autosomal dominant disorder characterized by the continuous development of multiple benign skin appendage tumors. It is treated usually by repeated standard surgery. Here, we present a case study where electrochemotherapy (ECT) with bleomycin was used as an effective alternative approach in treating advanced dermal cylindromatosis of the head and neck in a patient with Brooke-Spiegler syndrome.

There have been unpublished reports of a follicular dysplastic syndrome in adult white-tailed deer (; WTD), known colloquially as "toothpaste hair disease." The current report aims to describe the gross and histologic lesions in skin samples from 2 adult WTDs that presented to the Wisconsin Department of Natural Resources and the Wisconsin Veterinary Diagnostic Laboratory with reports of hair loss in 2018. Both cases were grossly alopecic with sparing of the distal extremities and variably the head and neck.

Background: Nevus sebaceous of Jadassohn is defined as a rare congenital malformation characterized as a non-hereditary hamartoma of the adnexal structures of the skin. Its etiology is not yet well understood, but it is believed to be related to post-zygotic mutations in the HRAS, NRAS and KRAS genes.
Objective: To describe the clinical manifestation of nevus sebaceous, as well as the main management techniques addressed in the medical literature.

Fibrosing alopecia pattern distribution (FAPD) is a recently described disease, wherein the clinical, trichoscopic, and histologic characteristics of non-scarring alopecia, such as androgenic alopecia, and lichenoid inflammatory cicatricial alopecia are reported. The lack of uniformity in the diagnostic criteria can result in FAPD overdiagnosis. The characteristic findings of loss of follicular openings on trichoscopy and fibrosis on histopathology are crucial, as they are necessary to diagnose cicatricial inflammatory lichenoid alopecias.
