Primary squamous cell cancer (SqCC) of breast is a rather rare disease. These tumors are known to be quite aggressive in nature and are usually found to be treatment resistant. Currently there is no standard treatment guideline for management of primary SqCC of breast.
In this case report we present a case of primary SqCC of breast in a 60-year old postmenopausal women presenting as pigmented lesion over right breast (no lump). Initial skin biopsy (core) done by dermatologist revealed squamous cell cancer in situ (Bowen’s disease); however surgical resection of the lesion and subsequent histopathological examination revealed primary SqCC (no secondary sites were found elsewhere in the body).
