Leiomyosarcoma: A rare soft tissue cancer arising from multiple organs

Leiomyosarcoma (LMS), a smooth muscle connective tissue tumor, is a rare form of cancer which accounts for 5–10% of soft tissue sarcomas. This type of cancer is highly unpredictable. LMS is a resistant type of cancer and can remain in the dormant state for long time. It can recur in the later stages of life. LMS has been reported in different animals including humans. A wide literature search was done. The PubMed database was used to search for journal articles on the occurrence of LMS in different organs from 1950 to 2016. LMS has been reported to be associated with different organs, including esophagus, stomach, intestine, anus and uterus. In this article, an attempt has been made to review the studies based on occurrence of LMS with respect to the organs affected and frequency of publications. Finding the organ-associated occurrence of LMS may be useful in assessing the overall risk and formulating future cancer preventive strategies.

Radiation-induced leiomyosarcoma of the oral cavity: A rare occurrence detected on 18F-FDG PET/CT

Radiation-induced sarcomas (RIS) or postirradiation sarcomas have been reported as a rare long-term complication of radiation therapy (RT). The survival benefit offered by radiotherapy has been masked by an increase in the incidence of these sarcomas, thus making radiotherapy a double-edged sword. RIS generally develop with a mean latency period of 10-15 years and encompass different histological types. We report a case of oral leiomyosarcoma with a rather short latency period of 4 years after the radiotherapy of the prior oral squamous cell carcinoma (OSCC) detected on fluorine-18 (18F)-fluoro-2-deoxy-D-glucose (FDG) positron emission tomography/computed tomography (PET/CT). The rarity of occurrence of leiomyosarcoma in the oral cavity is also highlighted.

Primary intracranial leiomyosarcoma of the torcular Herophili associated with Fanconi anemia and allogenic stem cell transplantation

Fanconi anemia is associated with a high risk for developing malignant tumors. The occurrence of primary intracranial leiomyosarcoma, however, which in general has a poor prognosis, has not been described thus far. The purpose of this study is to report on management and outcome of leiomyosarcoma of the torcular Herophili associated with Fanconi anemia in a pediatric patient. A 12-year-old girl with Fanconi anemia presented with a primary intracranial leiomyosarcoma arising from the torcular Herophili and infiltrating the adjacent venous sinuses after previous allogenic hematopoietic stem cell transplantation. Radical tumor resection followed by radiotherapy resulted in tumor-free survival and good outcome at a 2-year follow-up. Despite occurrence of leiomyosarcoma in a site thought unfavorable for surgery, combined tumor resection and radiosurgery may yield excellent outcome.

Leiomyosarcoma of the pinna: a case report

Leiomyosarcoma is a malignant tumor that can arise from smooth muscle or from pluripotential, undifferentiated mesenchymal cells. In the head and neck, smooth muscle is sparse and found mainly in the walls of blood vessels and the erector pili muscles of the skin. The occurrence of leiomyosarcoma in the head and neck region is rare. The purpose of this report is to describe a case of leiomyosarcoma of the pinna. To our knowledge, the present case is only the second case of leiomyosarcoma of the pinna reported.
