Objective: To analyze the clinical features and prognosis of patients with cutaneous melanoma. Methods: The clinical data and follow-up data of 125 patients with cutaneous malignant melanoma (CMM) treated in the Tongji Hospital of Tongji Medical College of Huazhong University of Science and Technology between February 2008 and August 2019 were collected. Kaplan-Meier method and Log rank test were used for survival analysis, and Cox proportional risk regression model was used for impact factor analysis. Results: Among the 125 patients, 12 were stage Ⅰ, 62 were stage Ⅱ, 30 were stage Ⅲ, and 21 were stage Ⅳ; 76 were acral and 49 were non-acral. The median survival time was 44 months, and the 1-, 2-, and 5-year survival rates were 85.4%, 63.2% and 38.7%, respectively. Kaplan-Meier univariate survival analysis showed that Karnofsky performance status score, tumor stage, primary site, vascular infiltration, Ki-67, BRAF, lactate dehydrogenase (LDH), and surgical treatment were related to the prognosis of patients (P<0.05). The median overall survival (OS) time of patients receiving interferon treatment was 53 months, which was better than 40 months of patients not receiving interferon treatment, but the difference was not statistically significant (P=0.448). Among stage Ⅲ patients, the median OS time of patients receiving interferon therapy was 40 months, which was better than 17 months of patients not receiving interferon therapy (P=0.012). Among stage Ⅱ patients, the 1-, 2-, and 5-year survival rates of acral patients were 97.1%, 84.7%, and 65.8%, and the 1-, 2-, and 5-year survival rates of non-acral patients were 93.3%, 70.0% and 17.0%. The prognosis of patients with stage Ⅱ acral type was better than that of non-acral type (P=0.043). The median survival time of stage Ⅲ patients with acral type was 32 months, better than 17 months of non-acral type, but the difference was not statistical significance (P=0.164). The median survival time of acral type and non-acral type was 8 months and 11 months respectively (P=0.458). Cox multivariate analysis showed that tumor stage and preoperative LDH level were independent prognostic risk factors for cutaneous melanoma. Conclusions: Interferon treatment can improve the prognosis of patients with stage Ⅲ, and stage Ⅱ acral type patients have better prognosis than that of non-acral type patients. Tumor stage and preoperative LDH level were independent prognostic risk factors for cutaneous melanoma.

Primary malignant melanoma of the esophagus (PMME) is an extremely rare tumor with only scattered cases reported. Although surgical resection has been considered as the best possible option, the prognosis has been nonetheless poor. We report a case of PMME which was treated by surgical resection and additionally followed by chemotherapy. A 60-yr-old man underwent an esophagoscopy due to a 3-month history of dysphagia and upper abdominal discomfort. A pigmented polypoid mass in the lower third of the esophagus was discovered, and a biopsy identified the mass as a malignant melanoma. Consequently, a subtotal esophagectomy and intrathoracic esophagogastrostomy was carried out. At follow-up four months after discharge, lymph node enlargements in the cervical area and celiac axis area were found. As a result, the patients was started on systemic chemotherapy treatment, which included Dacarbazine. The patient has been doing well and is now 35 months post-operative.

Meningeal melanocytoma is a rare benign tumor with relatively good prognosis. However, local aggressive behavior of meningeal melanocytoma has been reported, especially in cases of incomplete surgical resection. Malignant transformation was raised as possible cause by prior reports to explain this phenomenon. We present an unusual case of meningeal melanocytoma associated with histologically benign leptomeningeal spread and its subsequent aggressive clinical course, and describe its radiological findings.

The authors report on a case of primary malignant melanoma of the 7th cervical spinal nerve root in a 45-year-old woman. Neuro-radiological features of this extra-dural mass were suggestive of a nerve sheath tumor. The lesion underwent total gross resection through the anterolateral approach. The patient's postoperative course was uneventful. Histopathological investigation confirmed malignant melanoma. There was no evidence of tumor recurrence or other melanotic lesions on regular follow-up examinations until the postoperative eighth month. When treating a common, benign-looking lesion of the cervical spinal nerve root, surgeons should be aware of the potential to encounter such a malignant tumor.

OBJECTIVETo summarize the clinicopathological characteristics of primary anorectal malignant melanoma (AMM).

METHODSClinical data of nine patients with AMM were reviewed retrospectively from January 1999 to March 2005.

RESULTSAnorectal malignant melanoma had a female predominance. The average age was 56 years old and average course of disease was 5.8 months. The onset of symptom was hematochezia, then anus prolapses. 94.7% of patients had AMM within 5 cm from anus margin; the average tumor size was (3.3+/- 2.1) cm. The polyp and ulcer were most common types. More than a half (54.5%) of the tumor was movable, 19.1% smooth surfaced, 6.6% soft textured. Synchronous metastasis was found in 14.0% of the patients, the first common metastasis was found in liver, the secondary was superficial inguinal lymph node metastasis. Half of the patients were misdiagnosed,and over 50% of patients were misdiagnosed as benign disease. Mile's operation was performed in most of patients (63%), while anal resection was performed in 30% of the patients.

CONCLUSIONSAnorectal malignant melanoma is often misdiagnosed,surgical procedure is the first choice for patients with AMM.

A mongrel male dog of three years old was referred to the Seoul National University Veterinary Teaching Hospital following a one month history of glaucoma. On ophthalmic examination, hyphema, glaucoma, uveitis, iridal mass, and loss of vision were noted in the right eye. Ultrasonography and computed tomography revealed a mass with involvement of the entire uvea. Radiographic evaluation did not reveal any evidence of distant metastasis. The right eye was surgically removed because of the high likelihood of neoplasia. A histologic diagnosis of malignant uveal melanoma was made.
