Dermoscopy of cutaneous smooth muscle neoplasms: a morphological study of 136 cases

2019

BACKGROUND: A variety of cutaneous smooth muscle neoplasms may arise in the skin and are frequently unrecognized by clinicians. There is sparse data relating to the dermoscopy of piloleiomyomas (PL), and nothing has been published about the dermoscopy of angioleiomyomas (AL) and leiomyosarcomas (LS). OBJECTIVES: To evaluate the morphological findings of a large series of cutaneous PL, AL and LS under dermoscopic observation, comparing these findings among them. METHODS: Digital dermoscopic images of 136 histopathologically confirmed cases of cutaneous smooth muscle neoplasms (114 PL, 13 AL and 9 LS) collected from 10 Hospitals in Spain, Austria and Italy were evaluated for the presence of d…

Immunoexpression of p53 in cutaneous and subcutaneous leiomyosarcomas.

2016

The diagnosis of malignancy in cutaneous and subcutaneous smooth muscle tumors is based on subtle criteria. Therefore, any ancillary technique useful in this differential diagnosis is always welcome. In this report, we study the immunoexpression of p53 in 19 malignant smooth muscle tumors of the skin (15 cutaneous leiomyosarcomas, 2 subcutaneous leiomyosarcomas, and 2 cutaneous metastases of leiomyosarcoma), as well as in 1 leiomyoma with cellular atypia, therefore complementing a previous study on p53 immunoexpression in leiomyomas of the skin. The p53 staining was positive in 12 (63.16%) of 19 leiomyosarcomas. Percentages of immunostaining in the positive cases varied from 2% to 95%. Ten …

Leiomyoma of the hard palate : a case report

2007

Leiomyoma is a benign smooth muscle tumor that is very rarely located in the oral cavity. It is accepted that the smooth muscle giving rise to this tumor corresponds to the tunica media of the arteries. The tumor can develop at any age, with no clear gender predilection, and typically manifests as a slow-growing, asymptomatic lesion. The diagnosis is based on the histopathological study, with the use of specific staining techniques, including immunohistochemical markers. Treatment consists of complete resection of the lesion, with due safety margins. We present the case of a 57-year-old male with a tumor located for the previous four months in the region of the hard palate, adjacent to the …
