Epithelioid angiosarcoma of the masseter muscle: a rare clinicopathological diagnosis.

Epithelioid angiosarcoma (EA) is a subtype of angiosarcoma which is a rare tumor of endothelial origin. Here, we report a case of 15-year-old boy who presented with soft tissue mass lesion in the parotid region mimicking as a benign parotid tumor. Cytology was suggestive of inflammatory swelling. Patient underwent superficial parotidectomy along with the wide excision of the swelling. On histopathology, it was diagnosed as EA. To the best of our knowledge this is the first case report of epithelioid angiosarcoma of the masseter.

Intraluminal Endometriosis: A Rare Entity.

The case presents an incidental finding of a rare variety of endometrioses in both the fallopian tubes termed intraluminal endometriosis in a 52-year-old female.

Post Cesarean Surgical Site Infection With Mycobacterium Abscessus Sp. Massiliense.

Objective: Surgical site infections (SSIs) owing to nontuberculous Mycobacteria (NTM) have emerged as an important cause of hospital-acquired SSI leading to great morbidity and mortality. Among NTM, Mycobacterium abscessus is reported in these sites. Epidemiology and transmission of M. abscessus in humans is noticing crux changes. Case report : We hereby describe a case of SSI after lower segment cesarean section (LSCS), presenting as a skin and soft tissue infection (SSTI) owing to a NTM. Conclusion: Clinicians should be aware of the possibility of infections caused by M. abscessus in patients who develop SSIs, particularly if they do not respond to conventional first-line antimicrobial therapy.

Not just skin deep: Multiple cutaneous nodules as first presenting sign of small cell cancer.

A 65 years old male, chronic smoker (30 pack years), presented with complaints of dyspnea (mMRC grade2), cough (dry in nature), loss of appetite, loss of weight ( > 5 kgs), weakness, bony pains, feverish feeling and easy fatigability for last 2-3 months.Contrast enhanced CT chest showed bilateral extensive paraseptal and centriacinar emphysematous changes, right upper lobe spiculated heterogeneously enhancing soft tissue lesion and significant conglomerate mediastinal lymphadenopathy encasing lower trachea and great vessels.As patient was high risk for development of pneumothorax related to image guided sampling of right upper lobe lesion in view of extensive emphysema; patient was referred to us for EBUS-TBNA (endobronchial ultrasound guided transbronchial needle aspiration) guided mediastinal lymph nodes sampling. But on head to toe examination revealed round, firm, non-tender, skin coloured, 2-3 cm size skin nodules (2 on left lateral chest wall, 1 on right lateral chest wall and 1 in proximity to umbilicus).Fine needle aspiration cytology (FNAC) was attempted from two of skin nodules which was suggestive of small cell lung cancerSkin metastasis as initial presentation is reported rarely in small cell lung cancer.The index case emphasize on importance of detailed physical examination in cases of lung cancer to look for any skin manifestation of the disease, although encountered rarely.Moreover detection of skin nodules helps in staging and prognosis of diseases.

Thymic amyloidoma mimicking sclerosing thymoma in a triple vessel disease patient: An incidental finding.

A 65 year old man who underwent coronary artery bypass graft (CABG) for triple vessel disease was found to have enlarged thymus. Biopsy of the thymic mass revealed localised amyloid deposits demonstrating strong apple green birefringence on polarised microscopy. Localized thymic amyloidosis is an extremely rare finding with present case as the seventh in the world and the first in India. Review of literature of thymic amyloidoma and its close differential sclerosing thymoma is hereby described.

Clinico-pathological spectrum of cutaneous sarcoidosis: an experience from a government institute in North India.

BACKGROUND AND AIMS: Sarcoidosis is a multisystem granulomatous disease of unknown etiology and cutaneous involvement is the second most frequent manifestation in systemic sarcoidosis.The aim of the present study is to evaluate the clinical and pathological spectrum of cutaneous sarcoidosis and compare the same with literature available. METHODS: The present retrospective study was conducted from January 2010-March 2015 and fifteen cases diagnosed as cutaneous sarcoidosis on biopsy were reviewed. The histological spectrum of cutaneous sarcoidosis was evaluated. RESULTS: The mean age at diagnosis was 46 years. Nine (60%) cases out of 15 were females. Most common cutaneous lesions were nodules (46.6%) followed by papules (40%). Classically, lymphocyte-poor, non-caseating epithelioid cell granulomas, was the most common histologic finding. Inclusion bodies were seen in 20% cases with occasional presence of fibrinoid necrosis (13.3%). Peri-adnexal granuloma, seen in one case, raised the possibility of tuberculoid leprosy. Foreign body was seen in one case supporting the opinion that sarcoidosis and granulomatous foreign body reaction are not mutually exclusive. Epidermal changes including atrophy, loss of rete pegs, acanthosis, papillomatosis, hyperkeratosis, parakeratosis and basal cell vacuolation were seen in 46.6% cases. Reticulin was positive in all the cases while special stains for acid fast bacilli and fungi were negative. CONCLUSION: The clinical presentation of cutaneous sarcoidosis may be variable. Presence of naked, reticulin-rich granulomas is the most characteristic histopathological finding. Correlation of clinical history with histologic examination is essential to exclude other granulomatous diseases including leprosy, syphilis, other infectious granulomatous diseases and foreign body reaction.

Kimura disease: case report and brief review of literature.

Kimura disease is a rare chronic inflammatory disorder of unknown cause, primarily seen in young Asian males. The disease is characterized by painless subcutaneous swelling, blood and tissue eosinophilia and raised IgE levels. Early diagnosis of Kimura's disease may spare the patient from unnecessary invasive diagnostic procedure. We describe a case of Kimura disease in a 14-year old male presenting with left submandibular swelling and also provide a brief review of the literature.

Thymic carcinoma - a rare case report.

INTRODUCTION: Thymic carcinoma is a rare, invasive mediastinal neoplasm with a tendency to metastasize. They constitute a heterogeneous group of tumors that present differently in terms of both behavior and prognosis. CASE REPORT: We present a case of thymic carcinoma in a 55-year-old male patient known to suffer from Myasthenia gravis, whose chief complaints were fatigability, ptosis and coughing. All electromyography studies were done along with excision biopsy to reach the definitive diagnosis. RESULTS AND CONCLUSION: The histopathological diagnosis of Thymic carcinoma-Lymphoepithelial variant was established. Though no definite staging system exists for the thymic carcinoma, prognosis of the patient was ascertained by using Weissferdt-Moran system, Masaoka and Tsuchiya TNM staging systems. Involvement of the pleural and the pericardial structures leads to poor prognosis, though no distant metastases or lymph nodal metastasis were evident.
