Folliculosebaceous-apocrine hamartoma

Folliculosebaceous-apocrine hamartoma is a rare, benign skin lesion that is characterized by an overgrowth of the hair follicle, sebaceous gland, and apocrine gland. It is considered a type of hamartoma, which is a benign tumor-like mass composed of an overgrowth of mature cells and tissues normally present in the affected part, but often arranged in an abnormal way.

Clinical Presentation

Folliculosebaceous-apocrine hamartoma typically presents as a solitary, small, skin-colored or slightly pigmented papule or nodule. It is usually located on the face or scalp, but can also occur on the trunk or extremities. The lesion is usually asymptomatic, but it can sometimes cause pain or discomfort.

Diagnosis

The diagnosis of folliculosebaceous-apocrine hamartoma is usually made based on the clinical presentation and histopathological examination of the lesion. The histopathological features include an overgrowth of the hair follicle, sebaceous gland, and apocrine gland, with the presence of dilated follicular and sebaceous ducts and cystic spaces filled with keratinous material.

Treatment

The treatment of folliculosebaceous-apocrine hamartoma is usually surgical excision of the lesion. This is usually curative, as the lesion is benign and does not have malignant potential. However, recurrence can occur if the lesion is not completely excised.
