Introduction:

Skin matrix tumors are rare tumors in the ENT area. In particular, the preoperative differentiation of benign from malignant neoplasms plays a significant role in the extent of surgical excision.

Case:

A 65-year-old female patient presented with initial painless, then suddenly increasing painful retro-lobular swelling, about 1.5 cm. An incision of the mass was already performed in another clinic on suspicion of an infected atheroma. Anamnestic consisted of a condition after otitis therapy in childhood. After excision of the mass in toto histologically a pilomatricoma could be secured. After long-term observation of 2 years, there was no recurrence.

Summary:

The Pilomatrixoma is a rare benign neoplasm of the hair follicle in the upper extremity, but can also appear as a palpable painless swelling in the head and neck area. The clinical, as well as morphological differentiation of this tumor entity from other malignant lesions, is difficult in many cases, especially as they can often be impressed as parotid tumors in the case of frequent preauricular localization. Malignant transformation of pilomatricomas is rare.
