A woman had 13 non-cancerous cysts on her scalp successfully removed in one surgery.

This study identified a germline variant in PLCD1 as a major risk allele for familial trichilemmal cysts, requiring a subsequent somatic mutation in the same allele for cyst formation.

This letter details 11 cases of scalp pseudocyst treated primarily with intralesional triamcinolone, resulting in complete hair regrowth in eight patients and self-resolution in some instances.

This case report described a facial hairline tumor initially diagnosed as a sebaceous cyst but ultimately confirmed as a rare Proliferating Pilar Tumor with focal malignancies upon histopathological examination.

In this case report, a 13-year-old girl with pilomatrixoma and mild polycystic ovarian changes was studied, but no direct correlation was found between the conditions, though shared hormonal and genetic factors suggest potential links warranting further research.

Surgeons should know about pilomatricoma for accurate diagnosis, even though it's rare.

This study introduces the term "hair matrix cyst" for a cyst with both pilomatricoma and epidermal cyst characteristics, highlighting its potential for misdiagnosis among similar skin conditions.

This study reviewed the literature on pilomatrix carcinoma and reported that while wide local excision was the most definitive treatment, local recurrences and metastases were common.

This discussion reviews the classification and naming of cutaneous cysts, proposing that cysts typically named cutaneous keratocyst and steatocystoma should be unified under the term "sebaceous duct cyst," but it reports no new clinical results.

This study described trichilemmal cysts, firm lumps that form from blocked hair follicles, typically found on the scalp but also less commonly on other body parts, affecting less than 10% of the population and possibly inherited as an autosomal dominant trait.
