title: Pseudoachalasia secondary to metastatic breast carcinoma mimicking radiation stenosis.
abstract: We reported on a rare case of pseudoachalasia secondary to metastatic breast carcinoma mimicking radiation stenosis. A 65-year-old woman was admitted to our department complaining of progressive dysphagia to solids and liquids. Her medical history revealed a surgery for left breast tumour, which had been performed 11 years, previously, with adjuvant treatment based on hormonal therapy and radiotherapy. The presenting symptoms had started 1 year before her admission, with progressive paradoxical medio chest dysphagia. The patient had lost 7 kg in weight without prominent anorexia. The endoscopic, radiological, histological and manometric appearance was in favor pseudoachalasia associated with stenosis of the esophagus. The esophageal mucosa covering the lumen of the stricture after the dilation was smooth and neoplasm was not detected by another repeated biopsy. We could not obtain the diagnosis for the stricture. The most likely diagnosis was a pseudoachalasia associated with esophagus stenosis complicating probably radiotherapy. The patient had received four pneumatic dilatations with several normal biopsies. At the last one (4 months later), pathological examination of the biopsy specimen revealed infiltrating lobular breast carcinoma. The final diagnosis was pseudoachalasia secondary to metastatic breast carcinoma mimicking radiation stenosis. Treatment was based mainly on tamoxifen.
