AIMS:To review the disease profile and treatment outcome of patients with primary skin malignancies treated at a regional cancer centre. SETTINGS AND DESIGN: Surgical oncology unit of a tertiary care regional cancer centre.Evaluation of treatment outcome of patients with skin cancer from Surgical Oncology database was done. MATERIALS AND METHODS: Retrospective analysis of records of 77 patients with skin cancers treated between 1995 and 2002 was conducted. Profile of patients with skin cancer, surgical details including the management of primary tumour, regional lymph nodes and reconstructive procedures performed and survivals were analysed. STATISTICAL ANALYSIS: All computations were done using the Statistical Package for Social Sciences (SPSS-9). Descriptive statistics were calculated in a standard fashion and survival analysis was performed using Kaplan-Meier method. RESULTS:Skin cancers constituted 2.4% (77/3154) of patients with cancer treated in the surgical oncology department. Squamous cell carcinoma (SCC) was the most common histological type (55.8%) followed by melanoma (26.1%) and basal cell carcinoma (BCC, 18.1%). Forty one percent of patients had undergone some form of intervention elsewhere before being referred. Reconstruction was required in 55.8% patients with large postresection defects. Regional lymph nodal dissection was required in 32.4% of total patients. Five-year median disease-free survival for the entire study population was 75%. CONCLUSIONS: Skin cancers constitute a small but significant proportion of patients with cancer. Unlike in the Western countries, SCC is the commonest histologic variety. Primary level inadequate intervention is very common. Optimal results can be obtained with radical surgery and optimal surgical margins along with a reconstructive procedure when needed.

Localized cystic disease of the kidney is a benign nonsurgical entity and presents with multiple cystic lesions in just one portion of the kidney or involves the entire one kidney. We report a case of localized cystic disease of the kidney in a 16 year-old-male. This patient underwent an ultrasound examination and incidentally found to have multiple cysts in the right kidney whereas the left kidney was normal. Diagnosis was confirmed by typical MRI findings, absence of any family history, normal results of urine analysis and renal function tests.

Cutaneous horn is a conical, dense, and hyperkeratotic protrusion that often appears similar to the horn of an animal. Giant cutaneous horns are rare; no incidence or prevalence has been reported. The significance of cutaneous horns is that they occur in association with, or as a response to, a wide variety of underlying benign, premalignant, and malignant cutaneous diseases. A case of giant cutaneous horn of left oral commissure along with carcinoma left buccal mucosa is reported here as an extremely rare oral/perioral pathology.

Background Hypoxia in patients with COVID-19 is one of the strongest predictors of mortality. Silent hypoxia is characterized by the presence of hypoxia without dyspnea. Silent hypoxia has been shown to affect the outcomes in previous studies. Research Question Are the outcomes in patients presenting with silent hypoxia different from those presenting with dyspneic hypoxia? Study design and Methods This was a retrospective study of a cohort of patients with SARS-CoV-2 infection who were hypoxic at presentation. Clinical, laboratory and treatment parameters in patients with silent hypoxia and dyspneic hypoxia were compared. Multivariate logistic regression models were fitted to identify the factors predicting mortality. Results Among 2080 patients with COVID-19 admitted to our hospital, 811 patients were hypoxic with SpO2<94% at the time of presentation. 174 (21.45%) did not have dyspnea since the onset of COVID-19 symptoms. 5.2% of patients were completely asymptomatic for COVID-19 and were found to be hypoxic only on pulse oximetry. The case fatality rate in patients with silent hypoxia was 45.4% as compared to 40.03% in dyspneic hypoxic patients (P=0.202). The odds ratio of death was 1.1 (95% CI 0.41-2.97) in the patients with silent hypoxia after adjusting for baseline characteristics, laboratory parameters, treatment, and in-hospital complications, which did not reach statistical significance (P=0.851). Interpretation Silent hypoxia may be the only presenting feature of COVID-19. Since the case fatality rate is comparable between silent and dyspneic hypoxia, it should be recognized early and treated as aggressively. Since home isolation is recommended in patients with COVID-19, it is essential to use pulse oximetry at the home setting to identify these patients.
