Cytological Diagnosis of Primary Cutaneous Nocardiosis in a Known Case of Lepromatous Leprosy, Syphilis and HIV
Nocardiosis is an acute, subacute or chronic bacterial
infection caused by a group of aerobic, gram positive
and weakly acid fast species of genus Nocardia.
Primary Cutaneous Nocardiosis (PCN) is relatively
uncommon disease and is usually seen in
immunocompetent persons. We report a case of
primary cutaneous nocardiosis in a known case of
lepromatous leprosy, syphilis and HIV patient who
presented with painful swelling over right thigh
Effectiveness of the International Consensus Group criteria for manual peripheral smear review
Context: The International Consensus Group for Hematology Review (ICGHR) are essentially review criteria designed to reduce the number of manual smear reviews following analysis in automated hematology analyzers (AHAs). Although AHAs are an indispensable part of the present-day clinical laboratory, manual smear reviews still play an integral role in identifying morphological abnormalities and to confirm the results of the analyzers. Aims: The aim of this study is to evaluate the efficacy of the ICGHR criteria and our laboratory criteria using the Sysmex XN-1000 for manual peripheral smear review (MSR). Study Design: A prospective cross-sectional comparative study between the two sets of criteria for MSR was performed. Material and Methods: A total of 860 whole blood samples sent over a period of 19 months for complete blood count testing to our laboratory were collected using systematic random sampling. Truth tables were prepared for each set of criteria. Tests of proportion were used to compare performance specifications between both sets of criteria. Results: Using ICGHR criteria, sensitivity was 81.58%, specificity was 84.61%, 83.38% positive predictive value, and 82.92% negative predictive value. The microscopic smear review rate was 47.56% and efficiency was 83.14%. Using our laboratory criteria, sensitivity was 98.80%, specificity was 41.40%, positive predictive value of 61.46%, and negative predictive value of 97.34%. The microscopic smear review rate was 78.14% and efficiency 69.30%. Conclusions: There was a significant reduction in the microscopic smear review rates using the ICGHR criteria compared to our laboratory criteria. The ICGHR criteria can thus be adapted to daily laboratory practice provided they are first optimized and locally validated before use
Acrokeratosis Verruciformis of Hopf: A Rare Case Report
Acrokeratosis Verruciformis of Hopf (AKV) is rare
autosomal dominant cutaneous dermatosis described
by Hopf in 1931. It is presented at birth but may appear
in early child hood; sometimes the onset may be
delayed until fifth decade of life. It usually presents
with multiple planar wart – like lesions, typically
observed on the dorsal aspect of the hands and feet but
may extend on to knees, elbows, forearms and also on
other parts of the body. The main differential diagnosis
is Darier disease and seborrheic keratosis which has
similar presentation. The unique finding of AKV is
Church spire elevation of epithelium which
differentiates from Darier disease. Due to the scarcity
of the cases here we present a case of AKV in a 29 year
old male which was diagnosed on clinical examination
and confirmed with histopathological examination.
We have made an attempt to describe histologic
features of AKV with differential diagnosis of these
lesions through review of literature
