Background: Panfolliculoma (PF) is a relative rare, benign follicular tumor comprised of all elements of the hair follicle, with a limited number of cases reported in the literature. Articles on the demographic and pathological analysis of this tumor are also lacking. Case presentation: In this report, we presented an unusual case of cystic PF on the back of a 14-year-old male, and we performed a thorough literature review and analysis of all previously reported cases. Conclusions: PF is a rare benign follicular neoplasm with characteristic differentiation toward all components of the hair follicle. In our analysis, PF occurred most frequently on the head region and was usually diagnosed in middle- to old-aged persons, with cystic PF being the most common histologic subtype. Since this tumor is rare and easily misdiagnosed as other tumors both clinically and pathologically, a thorough understanding of the histopathological manifestations and differential diagnosis of this tumor is necessary for both dermatologists and pathologists.
Background: Orf, or ecthyma contagiosum, is a zoonosis caused by Parapoxvirus that infects sheep and goats. Human transmission typically occurs in persons in contact with the infected animals or contaminated fomites and environment. In humans, it generally occurs as solitary or multiple skin lesions on the hands or fingers. Involvement of the head region has rarely been reported. Case presentation: We report an unusual case with multiple orf lesions on the scalp of a middle-aged woman, along with a review of previously reported Orf cases on the head region. Conclusions: Although Orf infection rarely happens on the head region, it should be considered in the differential diagnosis of cases with relevant animal exposure.
A 53‐year‐old woman presented with intermittent abrupt abdominal pain and occasional lower gastrointestinal bleeding for two years. She had taken a commercial Chinese tradition medicine (Da Chai Hu Tang) intermittently for health promotion for duration of five years. Idiopathic mesenteric phlebosclerosis was diagnosed by characteristic image findings including right side thread‐like calcifications on plain abdominal film, thickened ascending colon wall and venous calcification on computed tomography (CT) scans, and hyperechoic spots of thickened ascending colon wall on abdominal ultrasonography, which is reported for the first time in literature. The colonoscopy showed dark blue pigmentation on the mucosa around ulceration and loss of semilunar colon folds that is compatible to idiopathic mesenteric phlebosclerosis. Surgical intervention with right hemicolectomy was done for recurrent compromised symptoms. Her husband who took the same traditional medicine also was found to have the same disease in the following year. The toxic theory of idiopathic mesenteric phlebosclerosis was supported by two genetically irrelevant patients exposed to the same drug. Idiopathic mesenteric phlebosclerosis should be considered when image studies including ultrasonography show hyperechoic spots in thickened colon wall.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
