“…The current study included patients with pigmented skin phototype. However, in patients with skin phototype I‐III, the observed dermatoscopic findings especially the vascular structures can mimic nodulocystic basal cell carcinoma, amelanotic melanoma, adnexal tumours and B‐cell lymphoma . Basal cell carcinoma characteristically shows arborizing and short fine telangiectasia, unlike linear and branching vessels seen in our patients.…”

Background Leprosy, a chronic granulomatous infection has varied clinical presentations spanning across different spectrums. The scope of dermatoscopy is vast and has been studied for other granulomatous disorders like sarcoidosis.Objectives The objective of this study was to describe the dermatoscopic features of the entire spectrum of leprosy and to correlate with clinical and histopathological findings.Methods This was a prospective observational study of treatment na€ ıve leprosy patients over a period of 1 year. The study patients were categorized as per Ridley-Jopling classification based on clinical, slit skin smear and histopathological findings. Most representative lesions were photographed, evaluated by dermatoscopy and were biopsied.Results A total of 30 patients (21 males and 9 females) were recruited; 2 cases of tuberculoid leprosy, 12 cases of borderline tuberculoid (3 with type 1 reaction), 8 cases of borderline lepromatous, 6 cases of lepromatous leprosy (3 with type 2 reaction) and 2 cases of Histoid leprosy. The dermatoscopic featues consistently seen were yellowish orange areas and vascular structures like linear branching vessels and crown vessels correlating with the presence of dermal granulomas and dilated vessels. Broken pigment network, white chrysalis like areas were seen in addition. Tuberculoid spectrum also had absence of or diminished hair follicles and eccrine duct openings correlating with presence of peri-appendageal granuloma and appendageal destruction. Scaling and follicular plugs were other features in lesions of type 1 reaction.Conclusion Yellowish-orange areas and vascular structures are the common dermatoscopic features of leprosy. Broken pigment network and paucity of appendageal structures are additional specific features.

“…Cutaneous adnexal tumors (CAT) are rare benign or malignant tumors originating from adnexal epithelial parts of the skin such as pilosebaceous unit, eccrine or apocrine sweat glands [1]. It is a large group of tumors histopathologically classified as follicular, sebaceous, eccrine and apocrine tumors [2]. According to the new classification made by the world health organization in 2018, Paget's disease of the breast, extramamarian Paget's disease, anogenital breast-like gland adenocarcinoma, hidradenoma papilliferum, and anogenital breast-like gland fibroadenoma were also included in this group under the title of region-specific tumors [3,4].…”

Background/aim: Cutaneous adnexal tumors (CAT) are rare tumors originating from the adnexal epithelial parts of the skin. Due to its clinical and histopathological characteristics comparable with other diseases, clinicians and pathologists experience difficulties in its diagnosis.We aimed to reveal the clinical and histopathological characteristics of the retrospectively screened cases and to compare the prediagnoses and histopathological diagnoses of clinicians. Materials and methods:The data of the last 5 years were scanned and patients with histopathological diagnosis of CAT were included in the study.Results: A total of 65 patients, including 39 female and 26 male patients aged between 8 and 88, were included in the study. The female to male ratio was 1.5, and the mean age of the patients was 46.15 ± 21.8 years. The benign tumor rate was 95.4%, whereas the malignant tumor rate was 4.6%. 38.5% of the tumors were presenting sebaceous, 35.4% of them were presenting follicular, and 18.5% of them were presenting eccrine differentiation. It was most commonly seen in the head-neck region with a rate of 66.1%. When clinical and histopathological prediagnoses were compared, prediagnoses and histopathological diagnoses were compatible in 45% of the cases. Most frequently, it was the basal cell carcinoma, epidermal cyst, and sebaceous hyperplasia identified in preliminary diagnoses. Conclusion:Cutaneous adnexal tumors are very important, as they can accompany different syndromes and may be malignant. Due to difficulties in its clinical diagnosis, histopathological examination must be performed from suspicious lesions for definitive diagnosis.

“…In dermoscopy, we usually see aggregated white-yellowish globules in the center of the lesion with a surrounding crown of vessels. The latter usually present as branching vessels located along the border of the lesion which may extend toward the center but never cross it [1][2][3]. Arborizing vessels may be rarely seen in this lesion [3].…”

Arborizing vessels may be rarely seen in this lesion [3]. Dermoscopic vascular patterns of sebaceous hyperplasia are highly specific allowing a rapid diagnosis of this lesion.…”
