[Bilateral tumors of the eyebrows].
ABSTRACT We report about a 5-year-old boy who presented in our clinic with bilateral, slowly progressive solid tumors of the eyebrows. Histological examination of the excised tumors revealed the typical diversified picture of pilomatrixoma with basophilic and shadow cells. The bilateral or multiple manifestation of pilomatrixoma is uncommon and can be associated with myotonic dystrophy, sarcoidosis or Gardner's syndrome.

ABSTRACT: Pilomatrixoma, also known as calcifying epithelioma of Malherbe, is a benign skin neoplasm that arises from hair follicle matrix cells. Pilomatrixoma is a common skin neoplasm in the pediatric population that is often misdiagnosed as other skin conditions. This study reviews an 11-year experience at a tertiary children's hospital, examining the cause, clinical and histopathological presentation, management, and treatment outcomes of pilomatrixoma. A review of the pathology database at Children's Hospital Los Angeles revealed 346 pilomatrixomas excised from 336 patients between 1991 and 2001. The hospital charts, pathology records, and plastic surgery clinic charts were reviewed with respect to variables such as sex, age at the time of presentation, clinical and histopathological presentation, preoperative diagnosis, management, recurrence, and treatment outcome. The main presenting symptom was a hard, subcutaneous, slowly growing mass. The preoperative diagnosis was accurate and consistent with the pathological diagnosis of pilomatrixoma in only 100 cases (28.9 percent). This entity should be considered with other benign or malignant conditions in the clinical differential diagnosis of solitary firm skin nodules, especially those on the head, neck, or upper limbs. The diagnosis can generally be made with a clinical examination. Imaging studies are not required unless symptoms or the location of the lesion warrants such diagnostic assessments. The treatment of choice is surgical excision, and the recurrence rate is low.Plastic & Reconstructive Surgery 01/2004; 112(7):1784-9. DOI:10.1097/01.PRS.0000091160.54278.64 · 3.33 Impact Factor

ABSTRACT: Pilomatrixoma is an uncommon benign neoplasm that originates from the matrix of the hair root. It occurs more frequently in the head and neck region of children and adolescents, often involving the eyelid or eyebrow. Pilomatrixoma is often misdiagnosed clinically and the correct diagnosis can be established only after excision and histological examination. Pathologic diagnosis of pilomatrixoma is based on the finding of large masses of shadow cells, combined with basophilic cells, inflammation, foreign body giant cells, calcification, and ossification. We report 16 cases of eyelid pilomatrixoma that were treated in our department, and review the relevant literature.Survey of Ophthalmology 09/2008; 53(5):526-35.
