Journal of the American College of Cardiology. ? Leiomyosarcoma is a rare type of cancer that affects smooth muscle tissue. 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. There are irregular deposits of intensely basophilic acellular material in the dermis and subcutaneous tissue (figure 1). iii) Normal pouch with cuffitis? The STUMP belonging to the A category is the one most likely to behave in a malignant fashion according to Kempson's scheme.

Department of Pathology Stanford University School of Medicine. Knowledge of these tumors continues to evolve as information emerges about pathology, molecular genetics, and recurrence rates. This is a challenging case. They consist of disorganized proliferation of nerve fascicles, Schwann cells , and fibroblasts embedded within the scar tissue adjacent to the cut ends of the nerve. STUMP is diagnosed when atypical histologic features are found that range between leiomyoma and leiomyosarcoma . Figure 3. Follicular dendritic cell sarcoma (FDCS) is extremely rare and underdiagnosed, occurring primarily in lymph tissue and uncommonly in extranodal sites such as the spleen, liver, and tonsils [].Metastatic disease has also occurred, especially when the site of origination is the liver, affecting distant sites such as the lung and gastrointestinal system []. At 90 DPA frank neuroma formation was present in all stump tissue.

Click, smooth muscle tumors of uncertain malignant potential, WHO: uterine smooth muscle tumor that cannot be histologically diagnosed as unequivocally benign or malignant, Classify as none / mild or moderate / severe, based on nuclear pleomorphism, nuclear size, nuclear membrane irregularities, chromatin density and nucleoli size/prominence, No / mild atypia: uniform nuclei that may be enlarged, but with smooth nuclear contours, evenly distributed chromatin; minimal variation in nuclear size and shape, small nucleoli, Moderate / severe should be detectable at low power, Moderate atypia: large, plump and irregular nuclei with coarse chromatin; if 1 - 2 enlarged abnormal mitotic figures, call moderate atypia, Severe atypia: obvious pleomorphism, numerous cells with enlarged bizarre nuclei with dense chromatin; frequent giant cells, often multinucleated, enlarged and sometimes atypical nucleoli, Hairy extensions of chromatin must be present, extending from a central clot-like dense mass of chromosomes; hairy extensions from an empty center favor a non mitosis, Count 4 sets of 10 fields in area of highest mitotic activity, and use the highest count, Must rule out lymphocytes, mast cells, stripped nuclei, degenerated cells and precipitated hematoxylin, Presence or absence is powerful predictor of outcome for patients with uterine smooth muscle tumors, Must distinguish coagulative tumor cell necrosis and hyalinizing necrosis, Coagulative tumor cell necrosis: abrupt transition between necrotic cells and preserved cells; ghost outlines of nuclei of necrotic cells are often seen in necrotic area, but inflammatory cells are uncommon; common in clinically malignant smooth muscle tumors - DON'T IGNORE, Hyalinizing necrosis: zone of hyalinized collagen between dead cells and preserved cells, reminiscent of infarcted region organized by granulation tissue; eosinophilic collagen matrix common; if dead nuclei present, nuclei are uniform and chromatin is often faint, compared to nuclear hyperchromasia and pleomorphism in tumor cell necrosis; common in leiomyomas, Necrosis secondary to ulceration in submucous leiomyomas features acute inflammatory cells and a peripheral reparative process, whereas ghost outlines of nuclei are usually inconspicuous or absent, No / mild atypia, no tumor cell necrosis → leiomyoma, Moderate / severe atypia, no tumor cell necrosis → atypical leiomyoma if < 10 mitotic figures/HPF or leiomyosarcoma if 10+ MF/10 HPF, Moderate / severe atypia and tumor cell necrosis → leiomyosarcoma (mitotic figures don’t matter), Suggested to consider as tumor of low malignant potential because may recur (, Conservative because low likelihood of leiomyosarcomatous transformation (. spp.) Biopsy: ˝Neoterminal ileum ˛ Clinical: Restorative proctocolectomy and pouch.

This tumor should not be confused with the prostatic stromal tumor of uncertain malignant potential which may be abbreviated the same way ( STUMP ). Our study indicates that distinct expression patterns for p16, p53, and Ki-67 exist between leiomyosarcoma and usual LM and CLM (P<0.0001). had cancer in other St. Louis, MO: Elsevier; 2017.

Axonal regrowth was observed as early as 3 DPA and signs of unorganized axonal growth and neuroma formation were evident by 28 DPA. By following nerve regrowth and neuroma formation after amputation we were able to identify 6 separate histological stages of nerve regrowth and neuroma development. Knowledge of these tumors continues to evolve as information emerges about pathology, STUMP is essentially a nondiagnosis, and it is fraught with frustration for clinicians and patients.
