An 80-year-old man presented with an asymptomatic, dome-shaped, pinkish-red nodule with central crater filled with heaped-up keratin involved the leg of 10 months duration. It has been excised with a suitable safe margin and sent for HP examination which was consistent with KA.
Pilomatricoma (Pilomatrixoma or Calcifying Epithelioma of Malherbe) is a benign tumour derived from the hair matrix cells. It usually presents as an asymptomatic, solitary, deep seated, firm subcutaneous nodule with normal or pinkish above skin. The overlying skin on stretching produces the “tent sign” with multiple facets and angles. Commonest sites are the face, neck or arms; however, the scalp, trunk and lower extremities may be involved. At times, pilomatricoma may have a bullous appearance as in the current case of a female presented with a large bullous lesion with positive transillumination on upper arm of six months duration. The tumour has been excised totally and sent for HP which revealed an encapsulated mass composed of solid masses of basophilic cells and eosinophilic shadow cells.

Surface telangectases were apparent on the surface of the tumor which has been present for about three months. The lesion has been surgically excised in toto for therapeutic and diagnostic purposes and revealed histologic changes consistent with the diagnosis of keratoacanthoma.
