Fine needle aspiration cytology (FNAC) of salivary gland lesions is a safe, effective diagnostic technique. Several amply illustrated reviews are available in the English literature. The reported diagnostic accuracy varies between 86% to 98%. The sensitivity ranges from 62% to 97.6% and specificity is higher from 94.3% to 100%. In this present study, we have analyzed 172 cases of salivary gland aspirates and the histopathological diagnosis was available in 45 cases. There was discordance in cytological and histopathological diagnosis in nine cases. Five cases had discrepancies in benign versus malignant diagnosis with four cases being false negative. The errors in these FNA diagnoses were due to sampling error, observational error and interpretational error. Therefore, this study illustrates high diagnostic accuracy of FNAC in salivary gland lesions and shows that FNAC offers valuable information that allows the planning of subsequent patient management.

GCTTS can be confused cytologically with giant cell rich lesions of bone and soft tissue and pigment containing lesions including melanoma. Ladybird cell is a characteristic feature seen in this lesion. Proper clinicoradiological correlation is essential before offering a diagnosis of GCTTS on cytology.

The cytologic features in twelve cases of giant-cell tumor (GCT) and five cases of giant-cell tumor of tendon sheath (GCTTS) diagnosed by fine-needle aspiration cytology (FNAC) are described. All of these cases were histopathologically confirmed. The aspirates of GCT are composed of a dual population of mononucleated spindle cell and multinucleated giant cells. The peripheral adherence of giant cells to the spindle cell is the feature of diagnostic significance in GCT. In GCTTS, the aspirate consists of a polymorphic population composed of mononuclear histiocyte-like cells, hemosiderin laden macrophages, foamy macrophages, and a few multinucleated giant cells. FNAC can be used as a diagnostic tool for an early and accurate detection of these two giant cell-rich lesions, since the cytologic features when evaluated in conjunction with the clinical and radiologic features are sufficiently diagnostic.

The molecular age histopathologist of today is practicing pathology in a totally different scenario than the preceding generations did. Histopathologists stand, as of now, on the cross roads of a traditional 'visible' morphological science and an 'invisible' molecular science. As molecular diagnosis finds more and more applicability in histopathological diagnosis, it is time for the policy makers to reframe the process of accreditation and re-accreditation of the modern histopathologist in context to the rapid changes taking place in this science. Incorporation of such 'molecular' training viv-a-vis information communication technology skills viz. telemedicine and telepathology, digital imaging techniques and photography and a sound knowledge of the economy that the fresh entrant would ultimately become a part of would go a long way to produce the Modern Histopathologist. This review attempts to look at some of these aspects of this rapidly advancing 'art of science.'

Patients with cystic fibrosis (CF) often are colonized by Aspergillus species in their respiratory tract, but invasive aspergillosis is a rare complication. We describe the autopsy findings of an infant with cystic fibrosis who had fatal disseminated aspergillosis. The causative agent was identified as A. penicillioides by molecular technique. To our knowledge, this is the first report of disseminated aspergillosis caused by A. penicillioides in any type of patient. The literature on invasive aspergillosis in patients with cystic fibrosis also is reviewed.

A retrospective analysis of lobectomy, pneumonectomy, cystectomy specimens (10 years) and stillbirth/neonatal autopsies (5 years) was carried out to analyze the histologic spectrum of congenital pulmonary developmental disorders/malformations. The autopsy data was analyzed to identify the lesions that are more diffuse and not amenable to surgical management. A total of 166 cases of pulmonary developmental disorders/ malformation were found. Out of 2,155 stillbirth/neonatal autopsies, there were 105 cases of pulmonary hypoplasia, 2 cases of congenital pulmonary lymphangiectasis, 2 cases of extralobar sequestration, and 3 cases of congenital pulmonary airway malformation (CPAM). Among the surgical specimens, there were 21 cases of CPAM, 11 cases of intralobar sequestration, 5 cases of congenital lobar emphysema and 17 cases of bronchogenic cyst. All these malformations have been described in reference to the latest updated classification of developmental disorders/malformations.

Visceral botryomycosis is rare, and documented sites are lung, brain, kidney, liver and prostate. This report describes a rare autopsy case of disseminated visceral botryomycosis, with bulky, grape-like botryomycotic vegetations in the heart, and similar abscesses in the lungs and bone marrow. This is the first such report in the literature to the best of our knowledge.

Congenital hyperinsulinism (CHI) is the most common cause of persistent hypoglycemia in infants and children. The pre-operative differentiation of focal from diffuse forms is extremely important from the management point of view. The current methods for pre-operative differentiation are invasive. We report a patient with CHI where somatostatin receptor scintigraphy was used to diagnose CHI but with limited^ -TQ ^ŝ uccess. A preoperative gallium DOTATOC-PET scan was performed which revealed highly localized radiotracer uptake in the body of the pancreas. 80% of the pancreas including the body was resected. The clinical problems did not completely resolve after surgery. Histopathology revealed hyperplastic islet cells at the resected margin and randomly throughout the pancreas. This case highlights the use of 68 gallium DOTATOC-PET scan in a patient with severe CHI. The satellite foci that were missed may be either an inherent limitation of 68 Ga DOTATOC scan or an underinterpretation due to lack of expertise. This report opens up a new option of using somatostatin analogue scintigraphy for pre-operative localization of hyperplastic islet cells in patients with CHI.
