“…A study by Moehlenbeck FW showed that nearly 60% of the patients with pilomatricomas were less than 20 years of age (10). The majority (25, 80.6%) of the patients in this study were under 20 years of age.…”

Objective: To reassess diagnosed cases of pilomatricoma for presence of other matrical tumours, secondary changes and obtain related demographic data. Method:The histopathology reports and slides of thirty one diagnosed pilomatricoma cases were reassessed for the presence of other matrical tumours, tumour location and presence of secondary changes including, pattern of calcification, presence of pigmentation, mitosis, osseous metaplasia, secondary suppuration, presence of integral cystic structure, proportion of ghost and basophilic cells and giant cell tissue reaction.Results: Twenty five (80.6%) patients were under 20 years of age. Twenty three (74.2%) patients were females. The site of occurrence varied. The diagnosis of pilomatricoma was confirmed and retained in 23. Three and five cases were redesignated as matricoma and pigmented pilomatricoma respectively. The presence of secondary features also varied. Conclusion:It is essential to look for the presence of additional features besides the diagnostic features of a pilomatricoma so as to give the appropriate name to the entity.

Pilomatricoma is a benign, usually asymptomatic neoplasm that arises from the hair follicle matrix cells. The lesions usually appear as firm, solitary or multiple tumors of the dermis. It was initially described by Malherbe and Chenantais in 1880 as a calcifying tumor that originates from the sebaceous glands. Forbis and Helwig were the first to advocate the use of the term pilomatricoma for such tumors (1, 2).Pilomatricoma is commonly found on the face and upper extremities and they demonstrate a peak age at the first and sixth decades of life. However, 60% of the cases occur within the first two decades of life (3 5).The female to male ratio is about 3:2. Generally, pilomatricoma is not hereditary: however, multiple tumors occur in about 3% of the cases as an autosomal dominant inherited disorder (6 9).

“…2 These tumours depict bimodal peak presentation during the first and sixth decades of life, however, 40% of cases occur in patients younger than 10 years of age and 60% of cases occur within the first two decades of life. 3 There is a female pre-ponderance for the affection of the disease. 4,5 The most common site of affection is head and neck area with more than half the reported cases in this area.…”

Malherbe’s calcifying epithelioma is a very rare benign tumour in area of cheek but generally present in first two decades of life. Fine Needle Aspiration Cytology (FNAC) and radiological imaging technique are not of great help in diagnosing this tumour. We hereby present a case of 15 year female with cheek swelling since 3 years which turned out to be pilomatricoma on histopathology of specimen of excisional biopsy. Keywords: Malherbe’s calcifying epithelioma, Pilomatrixoma, BCL-2, CTNNB1
