A Large Esophageal Leiomyoma: Thoraco-Laparoscopic Enucleation or Esophagectomy and Reconstruction?

BACKGROUND Esophageal leiomyoma is a rare condition, with an estimated incidence rate of 0.4% of all esophageal neoplasms. These tumors are typically small, rarely more than 5 cm. The treatment depends on symptoms and the size and location of the tumor, with enucleation as the standard treatment of esophageal leiomyomas. Esophagectomy is performed only in very few cases, such as when the tumor is too large, there are multiple leiomyomas, there is a horseshoe shape or circumference, or the tumor is inextricably adhering to the esophageal mucosa. In such complex cases, it is often difficult to perform enucleation. However, with the risks of esophagectomy and intra-thoracic anastomosis, namely reflux, stenosis, leakage, abscess, and infection, attempting to perform enucleation for these cases should still be considered. CASE REPORT We reported a case of a large, multi-lobed, circumferential esophageal thoracoabdominal leiomyoma with successfully performed enucleation and esophageal preservation. A Dor fundoplication and Witzel jejunostomy tube were also performed. Follow-up 3 months postoperatively showed no appearance of reflux or dysphagia. The postoperative esophagogram visualized no obstruction or leakage. Histopathological results gave us concrete evidence of a leiomyoma: elongated cells with eosinophilic cytoplasm and rhomboid nuclei with uniform size. CONCLUSIONS The thoraco-laparoscopic enucleation approach is the method that should be considered first in the treatment of large, multi-lobed, circumferential esophageal leiomyomas, before contemplating esophagectomy and reconstruction.

Malignant Melanoma of Anorectum: Two Case Reports.

Malignant melanoma of the anorectum is a rare disorder. Patients often present with local symptoms similar to benign diseases. The prognosis is very poor, and almost all patients die because of metastases. We report 2 female patients with unremarkable histories. Both of them received previous operations before visiting our center after they were diagnosed with anorectal malignant melanoma. One case underwent abdominoperineal resection and postoperative chemotherapy. The other had been treated with ultralow anterior resection followed by immunotherapy.

A Rare Colonic Metastasis Case from Hepatocellular Carcinoma.

BACKGROUND: Hepatocellularcarcinoma (HCC) metastasis include intrahepatic and extrahepatic metastasis. Similar to intrahepatic metastasis, extrahepatic metastases are not unusual in cases with HCC. However, colonic metastasis is infrequent. CASE REPORT: We describe a clinical case, he was diagnosed with HCC a year ago, treated with TACE (transarterialchemoembolisation), re-examined with abdominal pain and defecation disorder. The tests such as CT scan, colorectal endoscopy, fine needle aspiration (FNA) revealed secondary metastatic lesion of HCC in sigmoid colon. This is the first gastrointestinal (GI) tract metastatic we have encountered. CONCLUSION: HCC metastases of the colon are rare, especially cases of hematogenous spread. The prognosis of these patients is often very critical. Indications for surgical removal of the lesion may be used if the general situation of patient is acceptable.
