Pyopneumothorax with Stocker type III congenital cystic adenomatoid malformation in a 5-month-old infant.

Congenital cystic adenomatoid malformation (CCAM) is a rare, developmental, hamartomatous abnormality of the lung characterized by a cessation of normal bronchiolar maturation, resulting in cystic overgrowth of the terminal bronchioles. We report one such case of CCAM in a 5-month-old female infant who was in perfect health until she suffered from spontaneous pyopneumothorax with type III CCAM of the lung and recovered after lobectomy.

Malignant phyllodes tumor with chondrosarcomatous differentiation: radiological-pathological correlation.

We present a case of a 63-year-old woman with malignant phyllodes tumor in her left breast. On imaging, a large, dumbbell-shaped, predominantly cystic mass with thin peripheral enhancement was noted. The lesion was causing rib destruction, chest wall invasion, and intrathoracic extension.

"Metabolic signature" of the lesions on F18-fluoro-deoxyglucose positron emission tomography: A clue to the underlying pathology.

Increase in glycolytic pathway, forms one of the major adaptations in various cancer types. This can be imaged using (18)F-fluoro-deoxyglucose positron emission tomography/computed tomography (FDG PET). The intensity of FDG avidity is an indirect marker of the grade of the tumor.

Primary central nervous system lymphoma: a clinicopathological and cytomorpholgical study from a tertiary care centre in Chennai, India.

Background: The aim of this study was to analyze the clinicopathological and immunohistochemical features of primary central nervous system lymphoma (PCNSL) cases occurring in Indian patients and also study the utility of the crush smear preparation in intraoperative diagnosis.

Materials And Methods: The immune status, clinical, radiological details, immunohistochemical profile, histopathological findings and cytological features in smear preparation of 32 cases of PCNSL were analyzed. Patients with systemic NHL and skull-base lymphomas were excluded.

A unique case of well differentiated papillary mesothelioma involving an inguinal hernia.

Well Differentiated Papillary Mesothelioma (WDPM) is an uncommon tumor occurring predominantly in the peritoneum of young women with no history of asbestos exposure. In this report, we present a case of 48 year old male patient presenting with indirect inguinal hernia and incidental finding of a WDPM in the hernial sac during surgery. The unusual site of presentation and the relative rarity of this neoplasm in males evoke much clinico-pathological interest.

Images: granular cell tumour of the breast mimics a malignancy.

Five percent of granular cell tumour occurs in the breast. They are benign in nature but mimick a carcinoma on imaging (mammography and breast ultrasound). We present radilogical and histopathological images of granular cell tumour in the breast.
