Metastasis to the Male Breast from Squamous Cell Lung Carcinoma

Abstract EN

Metastasis to breast from extra mammarian organs is quite rare with an incidence of 0.5–3%.

Malignancies that most commonly metastasize to breast are lymphomas, leukemias, and malignant melanoma.

Metastasis of lung cancer to breast is a very rare condition.

We present here a case with squamous cell lung cancer that metastasized to breast.

A 65-year-old man presented with cough in addition to a mass in the left breast, which had been noted 3 weeks ago and grown gradually since then.

A histopathological diagnosis of metastasis of squamous lung cancer was made for the mass in the left breast.

PET/CT scan showed no distant metastasis.

Chemoradiation therapy was applied for lung cancer.

As the prognosis of such patients is extremely poor, it is of a great importance to distinguish a primary breast cancer from a metastatic breast lesion in order to determine the appropriate treatment modality.
