PURPOSE: Pilomatrixomas occur most often in the first 2 decades of life.(3)The recuency of pilomatrixoma was 1.04% of the all benign skin lesions.(4)There appears to be a 3:2 female:male incidence ratio, with Caucasians being the most affected group.The most common location of tumor is in the head and neck region. The prognosis is typically good, and the treatment of choice is surgical removal. We report a interestng case of an pilomatrixoma of the upper chest. In a sixth decade of her life

METHODS: A 46 year old caucasian femele with a six moth history of masses in the neck near of the clavicula, that had been growing for 6 months. Physical examination revealed a mass firm, painless. The overlying skin was elevated, flesh colored and soft. The remainder of the examination was unremarkable. She was treated with biopsia and surgical excision. The histopathological examinations confirmed the diagnosis of pilomatrixoma.

RESULTS: Pilomatrixoma malignant transformation is rare, and has been written approximately 90 cases in the bibliography. It’s frequently in middle age and elderly, especially in males and its localizated in the back of the neck and the top back. The 60% of the cases relapses if only implement a simple excision; it recommend to extend the margins of 1 to 2 cm. The added local radiotherapy is considerated a useful adjunctive treatment and considering that metastases are described (lung, lymph, liver, pleura, kidney and heart) and death for malignant pilomatrixomas.

CONCLUSIONS: The usual clinic presentation is a solitary and hard consistency nodule or stone should be calcified, localizated in the face and neck, upper extremities and sometimes rarely in chest

CLINICAL IMPLICATIONS: We report a interestng case of an pilomatrixoma of the upper chest. In a sixth decade of her life
