“…Diagnosing the former depends on positivity for h-caldesmon while diagnosing the latter depends on the presence of a skeletal muscle marker, such as myf-4 or fast myosin. Positivity for the S-100 protein and other melanocytic markers is useful in diagnosing a melanoma [1, 7, 8]. In our case, the tumor was positive for alpha 1-antichymotrypsin and vimentin.…”

Primary Undifferentiated Pleomorphic Sarcoma of the Colon Mesentery

An undifferentiated pleomorphic sarcoma (UPS), also known as a malignant fibrous histiocytoma in the past, commonly involves the soft tissue of the extremities and the retroperitoneum. However, a primary UPS of the colon mesentery is very rare. A 69-year-old male patient visited our outpatient department for treatment of an enlarged, palpable mass in the right lower quadrant (RLQ). Computed tomography showed a 15-cm multilobulated, heterogeneous, enhanced mass in the RLQ, which we suspected originated from the colon. He underwent a right hemicolectomy, and the pathologic result was a colon mesenteric UPS. We report a rare case of a primary UPS of the colon mesentery and discuss the characteristics of this neoplasm in reference to the literature.

“…It is extremely infrequent in adults and it accounts for less than 1% of all adult cancers [2]. The reported sites for primary RMS are head, neck, upper limbs [7], legs, trunk, pelvis [8], uterus [9][10][11], liver [5,12], ovary [13] and mesentery [14]. The omental tissue is of mesothelial origin, and it possesses stem cells' function, and angiogenic, immune and fibrotic activities.…”

Rhabdomyosarcoma (RMS) is a very rare, highly malignant neoplasm thought to originate from the pluripotent mesenchymal tissue. Predominantly diagnosed among children and teenagers, however they can also be encountered in adults. There are a few risk factors associated with RMS like family history of malignancy and genetic syndromes like neurofibromatosis type 1, Li-Fraumeni syndrome, Noonan syndrome and Beckwith-Wiedemann syndrome; however, most cases of RMS are sporadic. Other factors like radiotherapy for other malignancy and pre-natal radiation exposure also are associated with increased risk of developing RMS. The most common reported sites for RMS are head, neck, trunk, pelvis and lower limbs. Omental involvement of primary RMS has been rarely reported in the literature. Principally, the survival of treated RMS cases has improved, primarily due to multidisciplinary management approaches. In this paper, we report a case of primary pleomorphic RMS in a 50-year-old female who presented with abdominal pain.

“…There have been only a few cases of UPS in the gastrointestinal tract according to the diagnostic criteria after the WHO 2013 reclassi cation [4][5][6][7][8][9][10][11], and this is the second case with perforation of the gastrointestinal tract [4]. UPS lacks characteristic physical symptoms and imaging ndings.…”

Background: Undifferentiated pleomorphic sarcoma (UPS) in the gastrointestinal tract is rare. According to the diagnostic criteria after the World Health Organization 2013 reclassification, there has been only one case of UPS with perforation of the gastrointestinal tract.Case presentation: A 71-year-old man who was undergoing outpatient chemotherapy at the department of respiratory medicine of our hospital for lung cancer and brain metastasis, was admitted to our hospital with sudden high fever and abdominal pain. A computed tomography scan showed free air in the abdominal cavity with thickening of part of the jejunal wall. We suspected jejunal metastasis of lung cancer and performed emergency surgery for acute peritonitis due to gastrointestinal perforation in the same area. A Bormann type 2 tumor was found in the jejunum with perforation. The histopathological diagnosis was UPS. Ten months have passed since the surgery, and there has been no recurrence of UPS and no significant change in lung cancer.Conclusions: Primary UPS of the gastrointestinal tract is rare, and cases with perforation are extremely rare. Currently, ten months have passed since the surgery, and no recurrence has been observed. We encountered a case of UPS in which it was difficult to distinguish metastasis from lung cancer to the jejunum, and emergency surgery gave us the chance to confirm the definitive diagnosis and save the patient's life.
