Signs and symptoms
Diagnosis
Giant solitary trichoepithelioma is distinguished histologically by a dermal or subcutaneous tumor made up of basophilic cells grouped in solid, adenoid, or lace-like clusters. The cells have a sparse cytoplasm and a darkly pigmented nucleus, and the tumor islands exhibit the typical peripheral cell palisading. Papillary bodies and trichilemmal keratinization in horn cysts are indicative of a solid diagnosis, however they are not always present. Failures to develop papillary mesenchyme are represented by papillary bodies.[4]
Treatment
The preferred course of treatment is either radiosurgical ablation or surgical excision, with or without a flap.[4]
