RESUMO
Pulmonary Nodular Lymphoid Hyperplasia (PNLH) is a rare benign pulmonary disorder characterized by a localized, reactive polyclonal lymphoproliferation. Although the radiological features of this disease have not been clearly defined, they usually consist of a solitary non-cavitatory pulmonary nodule. In this report, we describe two cases of histologically confirmed PNLH presenting as multiple bilateral cavitatory lesions on CT Thorax.

A 72-year-old man presented with a two month history of rectal bleeding. Colonoscopy demonstrated synchronous lesions at 3 cm and 40 cm with histological analysis confirming synchronous adenocarcinomata. He developed bilobar hepatic metastases while undergoing neoadjuvant chemoradiotherapy. Treatment was complicated by Fournier's gangrene of the right hemiscrotum which required surgical debridement. Eight months later he re-presented with an ulcerating lesion on the right hemiscrotum. An en-bloc resection of the ulcerating scrotal lesion and underlying testis was performed. Immunohistological analysis revealed metastatic adenocarcinoma of large bowel origin. Colorectal metastasis to the urogenital tract is rare and here we report a case of rectal carcinoma metastasizing to scrotal skin.
