Synchronous squamous cell carcinoma of the stomach, the lung and the skin.

BACKGROUND

The incidence of multiple primary cancers is reported to be 0.3-4.3%.

METHODS

A 70-year-old man was admitted to the hospital because of fatigue, weight loss, epigastric pain with melena. A biopsy taken from a tumoral lesion in the gastric corpus revealed squamous cell carcinoma. A nodular lesion was also detected on the nasal columella and biopsy from this lesion also showed squamous cell carcinoma. Computed tomography performed as a part of metastatic work-up revealed a lesion in the left pulmonary lower lobe. Bronchoscopic biopsy from this lesion also demonstrated squamous cell carcinoma.

RESULTS

We report a case with synchronous squamous cell carcinoma of the lung, skin and stomach and discuss the multiple synchronous occurrence of carcinoma with the same histopathology in different sites with a review of the literature.
