Leiomyosarcoma of the larynx as a local relapse of squamous cell carcinoma--report of an unusual case

Leiomyosarcoma of the Penis: A Case Report and Re-Appraisal

BACKGROUND

Penile leiomyosarcoma arises from smooth muscles, which can be from dartos fascia, erector pili in the skin covering the shaft, or from tunica media of the superficial vessels and cavernosa. We describe presentation, treatment options, and recurrence pattern of this rare malignancy.

CASE PRESENTATION

We present a case of penile leiomyosarcoma in a 70-year-old patient who presented to the urology clinic with 1-year history of a slowly enlarging penile mass associated with phimosis.

CONCLUSIONS

Prognosis of penile LMS is difficult to ascertain because reported cases are rare. Penile leiomyosarcoma can be classified as superficial or deep based on tumor relation to tunica albuginea. Deep tumors (> 3 cm), high-grade lesions, and tumors with involvement of corpora cavernosa, tend to spread locally and metastasize to distant areas and require more radical surgery with or without postoperative radiation therapy. In contrast, superficial lesions can be treated with local excision only.

Kissing tumors; the concurrent diagnosis of leiomyosarcoma and squamous cell carcinoma of the esophagus

Background

Esophageal leiomyosarcoma (LMS) is a rare tumor that constitutes less than 1% of all malignant esophageal tumors. Concurrent occurrence of esophageal leiomyosarcoma with squamous cell carcinoma (SCC) is even rarer than isolated leiomyosarcoma.

Case presentation

In this report, we present a case of concurrent leiomyosarcoma and SCC in a 64-year-old woman presenting with vomiting and solid dysphagia, which has not been properly diagnosed following several referrals and diagnostic modalities. At last Exploratory laparotomy with gastric pull-up was performed in addition to radical laryngectomy with partial resection of the esophagus and subtotal thyroidectomy. Pathologic evaluation of the surgical specimen showed concurrent LMS (5.2 × 4.5 × 3 cm) and SCC (1.5 × 0.6 × 0.6 cm) at the same anatomical level in the proximal esophagus.

Conclusions

This study proposes the importance of using ancillary diagnostic tests such as immunohistochemistry (IHC) to diagnose less common cases such as concurrent LMS and SCC.
