Tubular adenomas of the breast: a rare diagnosis

Tubular adenomas of the breast are rare benign tumours and few cases have been reported. Most often, the tumours are described as palpable, well-circumscribed masses in women of childbearing age and are commonly diagnosed as fibroadenomas both clinically and radiographically. Surgical excision is required for diagnosis and to prevent continuing growth. Here, we present two cases of these rare tumours, both with unusual presentations. The first case describes a very large specimen (10 cm x 9.5 cm x 4 cm mass) with tubular adenoma pathology, which is one of the largest reported in medical literature. The second case illustrates another rare specimen, a mixture of both tubular adenoma and fibroadenoma pathology. We elected to document these cases to assist in the management of these rare lesions. Our hope is that this will allow future physicians to better identify and treat the pathology with improved outcomes for these patients.
