Common Presentation with Uncommon Diagnosis: Multifocal Epithelioid Hemangioendothelioma.

A young female patient presenting with recurrent hemoptysis, neck swelling, and mediastinal mass mimicking lymphadenopathy was admitted to the Institute of Post Graduate Medical Education and Research and SSKM hospital, Kolkata, India. Clinical features, radiological studies, fibre optic bronchoscopy, and fine needle aspiration cytology from the neck swelling created a diagnostic dilemma until surgical resection and immunohistochemistry reports confirmed the diagnosis of multifocal epithelioid hemangioendothelioma, a rare vascular tumor with intermediate malignancy potential. Because it is a slow-progressing disease and due to the non-availability of standard chemotherapy, the patient, and her legal guardian, opted for palliative care only. She was asymptomatic for four years but again presented with hemoptysis, reappearance of the neck swelling on the same side, and a mediastinal mass compressing the superior vena cava and right pulmonary artery. This report describes the diagnostic problems and therapeutic challenges in the management of this rare tumor over a four-year follow-up period. The clinical course emphasizes the highly unpredictable nature of this tumor.

Ancient schwannoma of vagus nerve mimicking hamartoma.

Schwannomas arising from vagus nerve sheath are rare mediastinal neurogenic tumours. Schwannomas usually arise from left hemithorax. Unlike a hamartoma, radiologically, calcification is rarely seen in schwannomas. We present the rare case of an ancient schwannoma arising from vagus nerve sheath from the right hemithorax presenting with gross calcification.

Pulmonary renal syndrome in a case of Wegener's granulomatosis.

We report a case of a 42-year-old patient who presented with Wegener's granulomatosis complicated by pulmonary renal syndrome, i.e., diffuse alveolar haemorrhage and rapidly progressive crescentic glomerulonephritis. The patient was treated with plasmapheresis and immunosuppressive drugs--intravenous cyclophosphamide and methyl prednisolone. The clinical, haematological and biochemical parameters improved substantially and remission is achieved.

Primary Lymphoepithelioma-like Carcinoma of the Lung in a 13 year old Girl.

Lymphoepithelioma-like carcinoma, a large cell carcinoma with pronounced lymphocyte infiltration, is a rare entity mostly seen in the nasopharynx. But primary pulmonary LELC in children & adolescents is extremely rare. Here we present a 13 year old girl with chief complaint of fever, cough, shortness of breath and heaviness in the left side of chest. She underwent left upper lobectomy. Histopathological examination of the biopsy specimen confirmed it to be a case of large cell carcinoma of lung, lymphoepithelioma type, invading pleura (stage pT3N0M0) with high serum titre of anti Epstein-Barr virus IgG antibody.

Squamous cell carcinoma lung with progressive systemic sclerosis.

Association between progressive systemic sclerosis (PSS) and lung malignancy is rare yet well recognised. In order of frequency bronchioloalveolar carcinoma (BAC) is most common followed by squamous cell carcinoma, oat cell carcinoma, anaplastic carcinoma of lung. We present a 55 year old non-smoker male patient with PSS, who presented to us with progressively increasing shortness of breath and dry cough. Initially clinico-radiologically he was provisionally diagnosed as a case of non-resolving pneumonia. Subsequent investigations revealed it is a case of squamous cell carcinoma of lung with PSS.
