This study found that androgen receptor activation in adult mouse skin reduces β-catenin-induced hair follicle growth and sebaceous gland conversion, highlighting its role in stem cell fate decisions.

This report highlights two cases where trichoblastoma in the breast was initially misdiagnosed as malignancy due to diagnostic challenges in needle core biopsies, emphasizing the importance of expert dermatopathologic review.

The document lists dermatology topics across life stages and notes hair loss can affect self-esteem and early skin cancer treatment is crucial.

This article reports on three new cases of Birt–Hogg–Dubé Syndrome and emphasizes the role of genetic analysis in its diagnosis due to clinical challenges.

This review discusses the biology of antiandrogens and highlights available bioassay models to predict their therapeutic effects on human skin, reporting no new clinical results.

This study found that benign tumors with a high risk of malignant progression primarily arise from hair follicle cells when a mutant ras gene is expressed in a specific population of epidermal cells in mice.

This study found that skin adnexal tumors are mostly benign, with 98.6% of cases being non-cancerous, and highlighted histopathological examination as essential for accurate diagnosis and management, given their frequent clinical misdiagnosis.

This case series highlights that nail clipping can aid in early detection and surgical planning of onychomatrical tumors by distinguishing between benign and potentially malignant growths based on the cavities' average dimensions.

This study found that continuous β-catenin signaling in adult mouse epidermis can reprogram hair follicles to form benign tumors, which regress after the signaling is discontinued.

In this study, among patients with clinically suspected appendageal tumours, histopathology confirmed their presence in 42 cases, with benign types found more frequently than malignant ones.

This study found that phospho-S6 is strongly expressed in malignant hair follicle tumors but only patchily in a minority of benign tumors, indicating a potential marker for distinguishing between the two.

This study observed that cancer patients had significantly lower immunity and higher virus infection and zinc levels in hair compared to those with benign tumors and healthy subjects.

This study observed that canine follicular tumors are an uncommon type of skin neoplasia in Croatian dogs, often benign but with a small percentage presenting malignancy, and vary based on the breed's hair growth type.

This study found that monoclonal antibodies identified distinct staining patterns in benign and malignant skin appendage tumors, highlighting their potential as markers for analyzing skin tumors.

This case report describes a rare instance of pilomatricoma, a benign tumor of the hair follicle, accompanied by striae distensae on a young man's flank, emphasizing the uniqueness of this presentation for timely diagnosis and care due to its potential for malignant transformation.

Different scalp conditions can lead to hair loss or tumors, with treatments varying from creams to surgery; early detection is crucial.

This case report describes the dermoscopic features of two cases of the tumor of the follicular infundibulum, contributing new insights as they had not been previously detailed in the literature.

This study reports that in a case of benign Brenner tumor, elevated androgens may originate from luteinized stromal cells, as these cells do not convert androgen to estrogen due to suppressed aromatase biosynthesis.

5α-reductase inhibitors can reduce prostate cancer risk but may increase high-grade tumors, needing more research.

This article reviews the types and characteristics of adrenal cortex tumors, including their hormone secretion and detection as incidental findings, but presents no new research results.

This study observed that finasteride use among men with benign prostatic hyperplasia was associated with a decreased incidence of low-grade prostate cancer but not high-grade tumors.

This study found that TGF-β1 expression in follicular tumors correlates with differentiation degree and suggests its potential role alongside p63 in differentiating between sebaceous and follicular tumors.

Finasteride is beneficial for BPH but requires careful monitoring due to cancer risks.

In this case report, a 7-year-old girl developed a painless, slowly growing keratinous cyst at her umbilicus, which was successfully resected and identified as a benign skin lesion; the authors emphasized the importance for clinicians to consider this diagnosis in pediatric umbilical tumors.

This case series detailed three postmenopausal women with ovarian steroid cell tumors, highlighting that such tumors may present asymptomatically or with virilization, and found surgery effectively normalized androgen levels, with distinctive imaging features aiding diagnosis.

This case study describes two postmenopausal women with severe androgen excess symptoms, diagnosed with ovarian hyperthecosis and stromal hyperplasia, emphasizing the challenges in differentiating these benign conditions from androgen-secreting tumors and the importance of surgical and histopathological evaluation for correct diagnosis and management.

This report describes cases of trichoblastoma and trichoepithelioma in mixed-breed dogs, highlighting their distinct microscopic characteristics without suggesting broader clinical implications.

This case report describes a postmenopausal woman with hirsutism and hair loss attributed to ovarian stromal hyperplasia; surgical removal of the ovaries normalized testosterone levels and resolved symptoms.

In this case report, a 48-year-old woman's hyperandrogenism, presenting with symptoms like acne and hirsutism, was attributed to a benign Leydig cell tumor, which resolved after surgical removal.

This case report suggests that intralesional cidofovir successfully treated SCC without systemic toxicity, making it a potential alternative to consider alongside surgical excision.
