This case report describes a 65-year-old postmenopausal woman with hyperandrogenism caused by a non-malignant ovarian Leydig cell tumor, which is a rare cause of virilization.

This case study describes a rare steroid cell tumor of the ovary in a 42-year-old woman, highlighting its virilizing effects and the importance of thorough follow-up due to its potential for malignancy.

This report describes two cases of nevus lipomatosus superficialis with the unusual feature of dilated hair follicles, emphasizing the need for precise histopathological diagnosis to differentiate from similar conditions.

In this case report, a preoperative core biopsy for a giant rhinophyma provided a misleading diagnosis, and the authors suggest such biopsies may be unnecessary.

This report discusses a case of an intradermal nevus in a 42-year-old woman and provides no clinical findings beyond a biopsy showing hyperkeratosis and cellular pigmentary changes.

In this case report, researchers described a postmenopausal woman with virilization symptoms who was diagnosed with a Leydig cell tumor in her ovary, and symptoms improved following tumor removal. The authors highlighted the diagnostic challenge of differentiating such cases from age-related hormonal changes.

This paper discusses the complex relationship between polycystic ovary syndrome (PCOS) and hyperprolactinemia, noting a decrease in prolactin levels following bromocriptine treatment, but reports no new clinical findings.

This case report describes a 23-year-old woman with an adult granulosa cell tumor of the ovary, whose symptoms and hormone levels improved significantly after surgical removal of the tumor.

This case report describes a rare instance of trichogerminoma with unusually numerous mitotic figures and a higher Ki67 proliferative rate, distinguishing it from previously documented cases.

In this case report, a 27-year-old woman with a swelling on her neck was initially misdiagnosed with squamous cell carcinoma, but was later identified as having pilomatrix carcinoma with lymph node metastasis, highlighting the importance of accurate diagnosis for effective treatment and prognosis improvement.

This report documents follicular dysplasia with pigmentary changes in two adult cows, contributing to the understanding of this rare condition in cattle.

This article describes pilar cysts, common dermal cysts often seen in young women, which typically require surgical removal.

This case report describes a strong dermoscopic and histopathological correlation in lichen nitidus, helping differentiate it from other similar conditions.

Cylindromas likely originate from hair follicle stem cells, not sweat glands.

In this case study, a 62-year-old woman with ovarian hyperthecosis experienced normalization of elevated testosterone levels and improvement in hirsutism and hair loss following bilateral salpingo-oophorectomy.

In this case report, researchers described how autoimmune thyroid disease can obscure primary hyperparathyroidism diagnosis, emphasizing the necessity of combining imaging, cytology, biochemical assessment, and parathyroid scintigraphy for accurate diagnosis.

This case report describes a postmenopausal woman with androgenic alopecia and progressive hirsutism who, despite normal imaging, had significantly elevated testosterone due to a Leydig cell tumor, revealed after surgical exploration; the condition improved post-surgery, underscoring the importance of considering such tumors in similar presentations.

This case report details a 73-year-old woman with significant hirsutism and hair loss linked to a rare ovarian Leydig cell tumor, which was resolved by bilateral salpingo-oophorectomy, normalizing her testosterone levels and addressing her symptoms.

This case report describes a woman with hyperandrogenism and menstrual disturbances, where an ovarian steroid cell tumor was identified and removed, leading to resolution of symptoms.

This study highlights a rare case of ovarian hyperthecosis in a 58-year-old postmenopausal woman, presenting with polycythemia and severe hyperandrogenism symptoms, with resolution of symptoms following laparoscopic bilateral oophorectomy.

The study found that, unlike in actinic keratosis and squamous cell carcinoma, basal cell carcinoma tissues showed higher expression of nidogen1 and Col4 in both basement membranes and surrounding stroma compared to normal skin.

This report describes two cases of aplasia cutis congenita with hair collar signs and hemangioma, which may suggest neural tube defects, although imaging showed no bone or neural tissue abnormalities.

This clinical case study reports on a postmenopausal woman experiencing hair loss and virilization symptoms, which were ultimately attributed to rare ovarian tumors identified after a bilateral salpingo-oophorectomy, despite normal imaging results.

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.
