Also reported in ureter and prostatic urethra. Contents. Surgical Pathology Criteria is focused on the presentation of useful diagnostic, grading and staging criteria in an accessible format. Traumatic neuromas may occur from acute or chronic injury to a nerve. Original posting/updates : 10/21/10. Smooth muscle tumor of uncertain malignant potential, abbreviated STUMP, is an uncommon tumor of the uterine smooth muscle that may behave like a benign tumor or a cancerous tumor. Clinical Features. 161, 162 Occasionally traumatic neuromas arise after relatively minor injury, such as injections for dental surgery. Objective: This retrospective study was designed to evaluate the clinicopathologic features and outcomes of a cohort of patients diagnosed with uterine smooth muscle tumor of uncertain malignant potential (STUMP) seen at a single institution. had cancer in other The Electronic Sarcoma Update Newsletter (ESUN) is an online peer-reviewed newsletter that contains articles of interest to sarcoma patients and their caregivers, physicians, and nurses.ESUN has an outstanding Medical Advisory and Editorial Board and is a vital source of information for thousands of readers worldwide.

The following outlines several of the basic steps commonly used to perform an uncomplicated BKA. 1989, 3, 1–84. TRAUMATIC NEUROMA: Traumatic neuroma is an exuberant non-neoplastic proliferation of nerve endings in response to trauma or surgery.In a severed or injured nerve, if the proximal and distal stumps are not approximated (or if there is no distal stump), haphazard proliferation of Schwann cells at the proximal stump gives rise to a traumatic neuroma. Uterine smooth muscle tumors of uncertain malignant potential (STUMP) represent a group of rare and challenging leiomyoma neoplasms. A freshly cut tree stump, 2 hours after cutting . Andrea Dall’Asta 1, Salvatore Gizzo 2, Andrea Musarò 1, Michela Quaranta³, Marco Noventa 2, Costanza . nodular hyperplasia / benign prostatic hyperplasia: Stromal neoplasms that involve only the prostate are divided into stromal tumor of uncertain malignant potential (STUMP), stromal sarcoma and carcinosarcoma, STUMP, prior to 1998, was termed atypical stromal hyperplasia (, Rare prostatic tumors with stromal degenerative atypia featuring vacuolated nuclei, May recur rapidly after resection; rarely progress to stromal sarcoma, STUMP occurs in a broad age range with median age of 58 years (, Usually presents with urinary obstruction, followed by hematuria, hematospermia and rectal fullness, Many STUMPs are incidental findings and behave indolently, A minority recur after surgery or metastasize, Up to 46% reportedly recur without definitive surgery (, Microscopically, STUMP should have rare to no mitotic activity and lack necrosis, Atypical stromal cells insinuate between benign acini, CD34 and cytokeratin are the most helpful immunostains, 34 year old man with prostatic stromal tumor with fatal outcome (, 56 year old man with recurrent prostatic stromal tumour of uncertain malignant potential (, 67 year old man with incidental prostatic stromal tumor of uncertain malignant potential (, Four patterns of STUMP have been described (, Hypercellular stroma with scattered degenerative atypia featuring vacuolated nuclei and smudged chromatin (50% of cases) (, Hypercellular stroma with bland spindle stromal cells, Benign phyllodes-like, similar to breast, with "leaf like" growth of hypocellular fibrous stroma surfaced by benign prostate epithelium, Myxoid stroma with bland cells, lacking the nodularity seen in benign hyperplasia (, STUMP may also have epithelial proliferations which mask its diagnosis: most commonly glandular crowding, prominent basal cell layer, prominent papillary infolding (, STUMP arises from specialized, hormonally responsive prostatic stromal cells, thus hormonal receptor immunostains may be positive.
