Peroperatively, we discovered a peritonitis secondary to a bulky perforated cecal tumor. We performed a right colectomy and an ileostomy. The posterior margin of the resection was macroscopically involved. The diagnosis of colonic schwannoma was confirmed with immunopathological examination of the surgical specimen. Surgical exploration 4 months later and morphological investigations during 2 years showed stability of the tumoral residue in the right iliac fossa. However, we noticed, on CT scanning control 2 years postoperatively, the appearance of a mesenteric recurrence. Exploratory laparotomy confirmed the unresectability of this mesenteric mass and showed the presence of multiple parietal nodules whose biopsies revealed their neurofibromatous nature. The 4 year follow-up of the patient didn't reveal any complication rather than need to right nephrostomy due to ureter compression by the primary tumoral residue.</p><p><strong>Discussion: </strong>Colonic schwannoma is a rare disease, commonly described in uncomplicated stages.

The conventional treatment for primary EMC is wide local excision with or without radiation therapy. Materials and Methods This study was a retrospective review of all EMC cases treated within a single institution between 1992 and 2019. EMC was diagnosed using a combination of histologic morphology and immunostaining, with confirmatory fluorescent in situ hybridization. Overall survival (OS) and disease-specific survival (DSS) were defined using Kaplan–Meier analysis. Results Fifteen patients were evaluated, including 11 males and four females. The average age at presentation was 51.7 ± 20.4 years and the mean follow-up time was 61.5 months (range, 5–286 months). The average resected tumor size at largest dimension was 7.14 cm (range, 2.4–18.7). Twelve of fifteen (80%) patients underwent wide local excision, and nine of the twelve (75%) underwent local radiation therapy. The 1-, 5-, and 10-year OS was 80% (95% CI, 59.8–100), 72% (95% CI, 48.5–95.5), and 72% (95% CI, 48.5–95.5), respectively. The 1-, 5-, and 10-year DSS was 92.3% (95% CI, 77.8–100), 83.1% (95% CI, 61.5–100), and 83.1% (95% CI, 61.5–100), respectively.

Approximately 20% of leiomyosarcomas are found in the GI tract, and account for 1–2% of GI malignancies. Within the gastrointestinal tract, the small intestine is the most common site of presentation followed by the colon. They are often diagnosed incidentally during abdominal pain investigation, and they usually present in the fifth decade of life. In the past, the diagnostic differentiation between leiomyosarcomas of gastrointestinal tract and gastrointestinal stromal tumors (GISTs) was very challenging as they share common microscopic appearance. Nowadays, these tumors are diagnosed by immunohistochemical methods as they are positive for smooth muscle markers actin (SMA) and desmin, negative for GIST markers such as receptor tyrosine kinase (KIT), CD34, DOG1, and negative for the schwannoma marker S100 protein. In the current literature, most cases of intestinal leiomyosarcomas are localized in the small intestine, and there are no reports of synchronous liver metastases at the time of presentation of the primary tumor.

Objective To evaluate the occurrence, clinico-pathologic spectrum, and patterns of orbito-ocular neoplasms as well as the treatment and outcome profiles. Methods A 5-year retrospective analysis of consecutive patients treated for orbito-ocular tumors. We evaluated patterns of occurrence, clinic-pathological concordance, and outcome of treatment. Associations were evaluated with chi square and confidence interval. Data analysis was performed using SPSS for windows version 23 and inferences were judged using the 95% level of significance. Results Among 100 patients with orbito-ocular masses, 62 were histologically confirmed. The female to male ratio (F:M) was 1.0. Their ages ranged from 7 months to 93 years, mean = 33.4 ± 2.7 years. There was an age variation among tumor types. Patients with squamous cell carcinoma (SCC) had a mean age of 46.4 years, while for retinoblastoma the mean age was 3.09 years. All patients with retinoblastoma had proven macroscopic orbital extension. SCC was the most common tumor type (n = 19), however, among children, retinoblastoma (n = 11) was more common. Melanocytic nevus, sebaceous gland carcinoma, and adenocarcinoma of lacrimal gland (n = 6, n = 5, n = 5), respectively, among other tumors were treated.
