RESUMEN
Leiomyomas are the most common benign mesenchymal neoplasms of the esophagus and constitute 04-1.5% of all tumours of this organ. We present a case of a 53-year-old woman with a single, small leiomyoma located in the cervical esophagus. The lesion was asymptomatic and unexpectedly revealed during esophagoscopy. The endoscopic electroresection of the tumour was performed. The patient remains well seven months after resection. The microscopic examination found a well circumscribed tumour composed of interlacing bundles of spindle cells with elongated cigar-shaped nuclei without pleomorphism showing positive immunostaining for desmin and a-smooth muscle actin.

We describe a case of a 50-year-old man with lesions localized in the region of urethral meatus and on the epithelium of the foreskin. The lesions were observed as the white spots with flat or somewhat depressed surface, locally similar to leukoplakia, lichen sclerosus atrophicus or cicatrix, without any subjective symptoms. Cystoscopy, micturition urography and biopsy were performed by urologist. The diagnosis of lichen planus Wilsoni was made based on the biopsy examination. We obtained great improvement of lesions through the applied local therapy
