Abstract

BACKGROUND/PURPOSE: Pilomatrixoma is a common tumor of skin appendages in children. The aim of the study was to assess the accuracy of clinical diagnosis and factors contributing to misdiagnosis.

METHODS

A retrospective case note review of patients who had pilomatrixoma excised during a 5-year period in a tertiary referral children's hospital in the UK.

RESULTS

From 75 patients, 78 pilomatrixomata were excised. The diagnosis was achieved preoperatively in 46% of patients. Other diagnoses included sebaceous and dermoid cysts, foreign body reaction, calcification in lymph gland, and fat necrosis.

CONCLUSION

Factors contributing to misdiagnosis include cystic lesions with varying consistency, punctum-like appearance, atypical location, and absence of clinically recognizable calcification. Despite close excision, the recurrence rate is low.
