Uterine smooth muscle tumors of uncertain malignant potential (STUMP) is a recently defined entity by the World Health Organization for a heterogeneous group of uterine smooth muscle tumors that cannot be histologically diagnosed as unequivocally benign or malignant 1.

Malignant tumors in fat are called liposarcomas. In smooth muscle around internal organs, cancerous sarcomas are known as leiomyosarcomas.

Leiomyosarcoma are malignant tumors of smooth muscle. They may be cutaneous and presumably arise from the arrector pilorum muscle, or subcutaneous, where they are believed to arise from vascular smooth muscle. Cutaneous leiomyosarcomas frequently reoccur following excision, but rarely metastasize. Pleomorphic or epithelioid cases may require desmin or caldesmon reactivity to support smooth muscle differentiation Any one of the following is sufficient to diagnose a smooth muscle tumor as malignant for the stated sites Cytologic pleomorphism or atypia A uterine leiomyosarcoma is a rare malignant (cancerous) tumor that arises from the smooth muscle lining the walls of the uterus (myometrium).

The soft tissues of the body include the muscles, tendons (bands of fiber that connect muscles to bones), fat, blood vessels, lymph vessels, nerves, and tissues around joints. Smooth Muscle Tumor of Uncertain Malignant Potential (used for any of below) Leiomyosarcoma (requires any one of below) Cytologically bland : Cytologic pleomorphism or atypia <1 mitotic figure / 50 HPF : Bland but 1-4 mitotic figures / 50 HPF >4 mitotic figures / 50 HPF : No tumor cell necrosis : Multiple recurrences but lacking other atypical Hair follicles are sometimes found surviving within the tumor. 14 The smooth muscle nature of the cells can be confirmed with the Masson trichrome stain or the use of immunoperoxidase markers for smooth muscle such as vimentin, smooth muscle actin (SMA), desmin, and caldesmon. 39 SMA is more specific for smooth muscle than panactin HHF35. Malignant smooth muscle tumor. Typically spindle cell, but can be epithelioid.

There is however another subtype of leiomyoma that is relatively uncommon. The World Health Organization (WHO) classifies this other subtype as a uterine smooth muscle tumor of uncertain malignant potential (STUMP) [1-4]. The term “STUMP” was first used in the literature Uterine smooth muscle tumors of uncertain malignant potential (STUMP) is a recently defined entity by the World Health Organization for a heterogeneous group of uterine smooth muscle tumors that cannot be histologically diagnosed as unequivocally benign or malignant 1.

Nevertheless, leiomyosarcoma is the most frequent malignant mesenchymal tumor of the uterus, accounting for almost 60% of uterine sarcomas. Tumors of muscular origin Dr Henry Knipe ◉ ◈ and Assoc Prof Frank Gaillard ◉ ◈ et al. There are a number of tumors of muscular origin, which overall are relatively uncommon, representing ~2% of benign soft tissue tumors and ~10% of malignant soft tissue tumors 1. The term smooth uterine muscle of uncertain malignant potential (STUMPs) indicates a group of uterine smooth muscle tumors (SMTs) that cannot be diagnosed unequivocally as benign or malignant. Diagnosis, surgical management, and follow-up of this neoplasm remain controversial, especially in pre-meno … Necrosis is common and tumors may undergo cystic degeneration; Immunohistochemistry: diagnosis confirmed by smooth muscle markers, such as actin+ and desmin+.
