Mucin histochemistry of heterotopic gastric mucosa of the upper esophagus in adults: possible pathogenic implications.

abstract：:We present a rare case of unilateral intratesticular cystadenocarcinoma with mucinous differentiation in a 71-year-old male patient. The orchiectomy specimen revealed a 3.5-cm well to moderately differentiated cystic neoplasm with elongated fine papillary structures lined by columnar epithelium with alternating goblet...
