Cutaneous changes in internal malignancy: Study from a tertiary care center.

BACKGROUND: A wide variety of systemic diseases and internal malignancies have cutaneous manifestations. In the context of internal malignancy, many cutaneous changes are highly specific to the underlying malignancy, while other changes are nonspecific. Some changes are also due to the modalities employed in the treatment of malignancies. METHODS: Two hundred and fifty patients who were diagnosed with internal malignancy and who were attending the department of radiation oncology, were evaluated at the Department of Dermatology, Sexually Transmitted Diseases and Leprosy of Government Medical College, Srinagar. The study was conducted over a period of 5 months. Relevant investigations, wherever needed, were carried out. RESULTS: Among the 250 cases examined, nonspecific cutaneous changes were seen in 39 (15.6%) cases, whereas specific skin lesions in the form of cutaneous metastases were seen in two (0.8%) patients. Nail changes and hair changes were also seen in some patients. LIMITATIONS: As this was a cross-sectional study and most of the patients were lost to follow up, we could not assess the outcome of the dermatological changes seen in the affected patients. CONCLUSION: Many dermatological changes are noticed early in the course of malignancy, reflecting a strong association of the cutaneous change with malignancy. Few manifestations occur late in the course of the disease, indicating dissemination or immunosuppression. Some changes reflect radiation-induced or chemotherapy-induced toxicity, indicating the need for treatment modifications.

MKK6 is upregulated in human esophageal, stomach, and colon cancers.

Expression analysis of MKK6 protein in solid tumors has never been investigated. Here, we report systematic analysis of MKK6 protein in different types of human tumor samples using western blotting and immunofluorescence techniques. We observed significant increase in the expression of MKK6 in Esophageal, Stomach, and Colon cancers as compared to controls. Results were alternately confirmed by Immunofluorescence studies. Upregulation of MKK6 protein is indicative of its role in human cancers and could possibly be used as a novel diagnostic or prognostic marker in these cancers.

Epidemiological distribution and incidence of different cancers in Kashmir valley--2002-2006.

There are no population-based data available on cancer pattern in Kashmir and our study is the first kind which represents the trend in cancer pattern in the valley. The source of our data were cancer patients registered in the Department of Radiation Oncology, Sheri-Kashmir Institute of Medical Sciences, Srinagar, and Department of Radiation Oncology, SMHS, Srinagar during the period Jan 2002 to Dec 2006. These are leading medical centres in the valley and draw most all of cancer patients from all over Kashmir for treatment. During the period a total of 6,943 cases were registered of which 4,345 were males and 2,598 were females. The age standardized incidence rates were 34.9 per 100,000 for males and 24.8 per 100,000 for females. Oesophagus was the leading site of cancer in both sexes (male ASR 11.2; female ASR 8.3) followed by lung (ASR 6.5), brain (ASR 2.2) and head and neck (ASR 2.2) in males and breast (ASR 5.2), skin (ASR 1.6) and rectum (ASR 0.95) in females. The incidence of cervical cancer in females and prostate cancer in males was lower in Kashmir as compared to other Indian registries. Overall cancer incidence was significantly lower and cancer patterns were markedly different in Kashmir. The observed cancer pattern indicates that awareness campaigns, life style and dietary habit changes, tobacco-control measures and early detection of breast cancer are very important for cancer control in this population.

Hughes-Stovin syndrome: A rare cause of hemoptysis.

Multiple pulmonary artery aneurysms are seen along with venous thrombosis in Hughes-Stovin syndrome, which many investigators believe is an incomplete form of Behcet's disease. We present a case of hemoptysis with multiple pulmonary artery aneurysms, femoral vein thrombosis, and oral ulcers with emphasis on its CT features.
