A man developed a benign tumor at his COVID-19 vaccination site, which was successfully removed with surgery.

A rare scalp condition called Erosive pustular dermatosis is hard to diagnose and treat.

Reflective confocal microscopy can potentially diagnose epidermoid cysts without a biopsy.

Scarring alopecia, a type of hair loss, is most common in females under 35, often caused by discoid lupus erythematosus and pseudopelade of Brocq. Skin punch biopsy and histopathology are key to identifying its cause.

The document concludes that central centrifugal cicatricial alopecia (CCCA) should be considered in African American men with vertex hair loss and scalp symptoms, and that prompt diagnosis and treatment can slow disease progression.

Older men with scalp wounds had long-term healing problems after using imiquimod or diclofenac for skin cancer prevention.

Understanding the cause of bitemporal hair loss is key to deciding the right treatment.

A man had a rare skin cancer that looked like a bald spot.

Biopsies matched initial diagnoses in 76.6% of black women with alopecia and led to treatment changes in 44% of cases.

Women with lupus experienced non-scarring hair loss with fewer hair follicles, and the test for lupus in hair was not helpful.

Biopsy can differentiate between alopecia areata and androgenic alopecia, and if more information is needed, testing for CD3 and CD8 can help.

Watching, not removing, skin growths with moderate atypia and positive edges is okay; patients may get melanoma elsewhere, especially if they've had it before.

Hair loss on the lower legs is common in middle-aged men, usually harmless, and doesn't need treatment.

Adults with persistent scalp issues unresponsive to typical treatments should be tested for the fungal infection tinea capitis to start the right antifungal medication.

A patient with patchy hair loss was successfully treated for Tumid Lupus Erythematosus after other treatments failed.

A woman with scalp lymphoma and hair loss improved with radiotherapy, highlighting the need for biopsies in similar cases.

Most skin cysts were common types found in unusual body parts, and examining tissue samples is important for accurate diagnosis.

A benign tumor developed at a girl's BCG vaccination site, not previously linked to the vaccine.

Pathologists need better education and collaboration with dermatologists for accurate alopecia diagnosis.

The study concluded that scalp tumors show different patterns based on age, gender, and tumor thickness, and emphasized the importance of early detection and scalp examinations.

Elderly patients with CCCA were all African American with low vitamin D, but no iron or zinc deficiencies, and no hormonal imbalances compared to younger patients.

Many people diagnosed with androgenic alopecia might actually have hidden scarring or inflammation.

A man with rare Lichen Planopilaris lost body hair, not scalp hair, and treatment stopped itching but didn't regrow hair.

African Americans have less hair density than whites.

Opioid use may lower PSA levels, suggesting a possible role in prostate cancer control; PSA testing is useful for detecting prostate cancer; serum triglycerides are not linked to prostate cancer risk; and higher urethral PSA levels may be associated with local hormone activity.

Lichen planus may be associated with a higher risk of metabolic syndrome.

Some men can have female pattern baldness without hormonal abnormalities or signs of feminization.

Possible causes of female hair loss include androgenetic alopecia, telogen effluvium, cicatricial alopecia, and alopecia areata incognita; diagnosis and treatment require dermoscopy and histopathology.

Androgenetic alopecia is a common hair thinning condition linked to genetics and hormones.

Some people have a genetic variation that makes them less effective at breaking down drugs.
