Objective: The aim of this study was to explain the clinical and histological spectrum of tumor in order to help for its better diagnosis. Patients and Methods: In a retrospective descriptive study, the clinical and histological features of pilomatricoma were reviewed.

Shadow cells, calcifications, ossification and granulomatous reaction were detected in 100, 50, 9 and 45.5 percent of specimens, respectively. The accuracy of clinical diagnosis compared with pathologic findings was 36.5 percent. Conclusion: Pilomatricoma was the final diagnosis in 0.55 percent of all biopsy specimens examined in Hamadan Sina Hospital between the years 1992 to 1999.
