Recognizing unusual patterns of hair loss helps dermatologists diagnose and manage Alopecia Areata better.

Rare adrenal cancers that secrete androgens or estrogens have a poor prognosis and are treated primarily with surgery.

Some cases of folliculotropic mycosis fungoides may progress slowly and not need aggressive treatment.

Krt15+ cells in mice can resist radiation, regenerate tissue, and start tumors, suggesting new cancer treatment targets.

The review found that basal cell carcinomas on the scalp are not more aggressive than those in other locations.

Women with PCOS have overall higher body fat, not abnormal fat placement, and more insulin resistance.

Different types of stem cells exist within individual skin layers, and they can adapt to damage, transplantation, or tumor growth. These cells are regulated by their environment and genetic factors. Tumor growth is driven by expanding, genetically altered cells, not long-lived mutant stem cells. There's evidence of cancer stem cells in skin tumors. Other cells, bacteria, and genetic factors help maintain balance and contribute to disease progression. A method for growing mini organs from single cells has been developed.

Disrupting β-catenin signaling in certain cells causes anorectal malformations.

CD73 may regulate hair growth and could be targeted for hair growth treatments.

Autoimmune conditions can be linked to trichoepitheliomas, with treatment focusing on cosmetic concerns.

A woman with thymoma developed a rare chronic condition similar to graft versus host disease after surgery.

Different types of polycystic ovary syndrome (PCOS) have varying severity, with Type I being the most severe and common.

Postmenopausal hyperandrogenism, a condition with symptoms like increased hair growth and acne, is usually caused by PCOS but can also be due to other factors. It's diagnosed by checking testosterone levels and treated either by removing the adrenal tumor or through antiandrogen therapy.

A specific group of immune and skin cells may cause chronic inflammation in atopic dermatitis.

The skin condition Ulerythema ophryogenes did not improve with treatment in a patient with other birth defects.

Dermoscopy helps accurately diagnose and treat benign skin cysts.

Steroid cell tumors in the ovary are rare, can cause hormone-related symptoms, and require surgery.

An 11-year-old Greek girl was diagnosed with a rare genetic disorder, highlighting the importance of genetic testing and family history.

Ovarian stromal hyperplasia can cause high testosterone in postmenopausal women and is treated by removing the ovaries.

Two teenage brothers had a rare, treatment-resistant form of female-pattern hair loss with unusual scalp changes.

A new mutation in the PLEC gene causes a rare condition with skin blistering, muscle weakness, and hair loss.

Classical PCOS types A and B are most common and linked to higher health risks.

Leydig cell tumors can cause high testosterone and symptoms in postmenopausal women, and removing them improves symptoms.

Ovarian tumors should be considered when postmenopausal women show signs of virilization.

A family showed a new condition with inherited hair loss and skin changes, possibly due to one genetic disorder.

Patients with one autoimmune disease should be checked for other autoimmune disorders.

RSPO1 mutations in certain patients lead to skin cells that don't develop properly and are more likely to become invasive, increasing the risk of skin cancer.

The author now believes tricholemmal carcinoma is a rare type of infundibular squamous cell carcinoma and more research is needed on these tumors.

Combining medication and minimally invasive techniques can effectively manage Marine-Lenhart syndrome.

A specific gene change plus an additional mutation in the same gene cause hereditary trichilemmal cysts.
