Filariasis is a major public health problem in tropical countries like India. Despite the large number of people at risk, detection of eggs with or without larva (microfilaria) on fine-needle aspiration cytology is very unusual, especially in an uncommon site or incidentally detected in clinically unsuspected cases of filariasis with the absence of microfilariae in the peripheral blood. A 19-year-old male presented with swelling over medial aspect of left arm (just above the elbow), with no other specific signs and symptoms...

Echinococcosis is a common cause of pulmonary cavities. Aspergillus fumigatus, a saprophytic fungus, can colonise pulmonary cavities caused by tuberculosis, sarcoidosis, echinococcosis, bronchiectasis and neoplasms. Infection by Aspergillus is often seen in immunosuppressed cases. However, co-infection of Aspergillus with pulmonary echinococcosis is unexpected and very unusual, especially in an immunocompetent patient. We present the case of a 45-year-old immunocompetent male who came with non-resolving pneumonia and fever for 8 months and dyspnoea since 15 days accompanied by recurrent episodes of hemoptysis since 5 days...

OBJECTIVE: Autofluorescence induced interference is one of the major drawbacks in immunofluorescence analysis of formalin-fixed paraffin-embedded tissues, as it decreases the signal-to-noise ratio of specific labeling. Apart from aldehyde-fixation induced artifacts; collagen and elastin, red blood cells and endogenous fluorescent pigment lipofuscin are prime sources of autofluorescence in vascular and aging tissues. We describe herein, an optimized indirect-immunofluorescence method for archival formalin-fixed paraffin-embedded tissues tissues and cryo sections, using a combination of 3-reagents in a specific order, to achieve optimal fluorescence signals and imaging...

Prurigo pigmentosa is a rare inflammatory dermatosis that primarily affects adolescents and young adults. Even though it is most commonly seen in Japanese women, other countries have reported cases with increasing frequency. It is characterized by erythematous papules and macules on the trunk, neck and chest that resolve leaving a reticulate hyperpigmentation. Some endogenous factors related with ketosis like fasting, diet, diabetes, pregnancy and exogenous agents like chrome, nickel, para-amino compounds have been accused of playing a role in etiology...

Seborrheic keratosis is a benign lesion that is common in the trunk and head and neck regions. It shows a considerable variety of histological appearances leading to different variants. The presence of sebaceous differentiation in seborrheic keratosis is very rare and can histologically mimic benign and malignant tumors with sebaceous differentiation. We present a case of a 65-year-old male presenting with multiple nodules over the right and left sides of neck and the right preauricular region, histopathological examination of which revealed multiple pigmented seborrheic keratoses with sebaceous differentiation...
