    Comparative cytological study of lymph node tuberculosis in HIV-infected individuals and in patients with diabetes in a developing country

    DIAGNOSTIC CYTOPATHOLOGY, Issue 2 2002
    C.B. Sridhar B.Sc., M.B.B.S., M.D.
    Abstract Tuberculosis (TB) is a common infection affecting patients with human immunodeficiency virus (HIV) and diabetes mellitus (DM). With the increasing incidence of HIV infection and DM in a developing country like India, TB is definitely on the rise. In a given population, one expects to see these three diseases in varying combinations, such as HIV and TB, DM and TB, HIV and DM with TB. In such combinations TB may lack the characteristic clinical and histological picture due to the associated depressed cell-mediated immunity seen in both diseases and TB may have an unusual clinical presentation and cytology picture. In this retrospective study of 36 months, from January 1997 to December 1999, 109 cases diagnosed cytologically as tuberculous lymphadenitis and tested for HIV infection and investigated as well for DM were selected. Forty-six (42%) were nondiabetic HIV patients, 13 (12%) were non-HIV DM patients, and 50 (46%) had TB without HIV infection or DM. The coexistence of both HIV and DM was not noted. The cytomorphological characteristics supplemented by culture studies of each of these three groups were compared in detail and based on these four cytological patterns, Pattern 1, Pattern 2, Pattern 3, and Pattern 4 emerged and were characterized. This study highlights the usefulness of cytomorphology of the lymph nodes to characterize the cytopathological profile of TB in both HIV and DM, which have many clinical and immunological similarities, and indirectly postulate the extent of immune suppression and evolve effective strategies in the management of coexisting diseases. Such a comparative study has not been carried out in the past. Diagn. Cytopathol. 2002;26:75,80; DOI 10.1002/dc.10059 © 2002 Wiley-Liss, Inc. [source]


    Fibrillar IgA deposition in dermatitis herpetiformis , an underreported pattern with potential clinical significance

    JOURNAL OF CUTANEOUS PATHOLOGY, Issue 4 2010

    Dermatitis herpetiformis has characteristic clinical and histopathologic findings. A fibrillar pattern of IgA deposition on direct immunofluorescence in dermatitis herpetiformis is underreported. Here, we describe three patients with the fibrillar pattern of IgA deposition on direct immunofluorescence examination that initially misled diagnosis in one of the three. Interestingly, two of the three patients lacked anti-transglutaminase and anti-endomysial antibodies but had a clinical course typical of dermatitis herpetiformis. Dermatitis herpetiformis may have a fibrillar rather than granular pattern of IgA deposition on direct immunofluorescent microscopy, and patients with this pattern of immunoglobulin deposition may lack circulating autoantibodies.

    Melanocytic matricoma: case confirmation of a recently described entity

    JOURNAL OF CUTANEOUS PATHOLOGY, Issue 4 2003
    Christy M. Williams
    Background:, In 1999, Carlson et al. reported two cases of a matrical neoplasm that recapitulates the bulb of the anagen hair follicle, which they designated as melanocytic matricoma. Methods:, Here we report a similar case in a 78-year-old white male, who presented with a 0.4 cm purple-black firm papule in the left preauricular area. Results:, Histologically, the tumor is composed of a dual cell population including admixed epithelial matrical and supramatrical cells with "shadow" cell formation and pigmented dendritic melanocytes. Immunohistochemical studies for cytokeratin highlighted the epithelial component and studies for S-100 protein, HMB-45, and vimentin confirmed the melanocytic component. The differential diagnosis considered includes pigmented variants of pilomatricoma, matrical carcinoma, basal cell carcinoma and malignant melanoma. Conclusions:, The case reported herein is the first confirmation of melanocytic matricoma, a distinctive adnexal neoplasm with characteristic clinical and pathologic features, which differentiate it from pigmented pilomatricoma.

    Clinical and genetic aspects of distal myopathies

    MUSCLE AND NERVE, Issue 11 2001
    David S. Saperstein MD
    Abstract Although most muscle disorders produce proximal weakness, some myopathies may manifest predominantly or exclusively distal weakness. Although several congenital, inflammatory, or metabolic myopathies may produce mainly distal weakness, there are several distinct entities, typically referred to as distal myopathies. Most of these are inherited conditions. The distal myopathies are rare, but characteristic clinical and histological features aid in their identification. Advances in molecular genetics have led to the identification of the gene lesions responsible for several of these entities and have also expanded our understanding of the genetic relationships of distal myopathies to other inherited disorders of muscle. This review summarizes current knowledge of the clinical and molecular aspects of the distal myopathies. © 2001 John Wiley & Sons, Inc. Muscle Nerve 24: 1440,1450, 2001 [source]


    Asymmetrical periflexural exanthem exhibiting pseudoisomorphic Köebner response in an adult

    CLINICAL & EXPERIMENTAL DERMATOLOGY, Issue 7 2009
    N. R. Dar
    Summary Asymmetrical periflexural exanthem is a rare clinical condition, seen almost exclusively in children. Very few adult cases have been reported in the literature. We report a case of this rare eruption in an adult man showing characteristic clinical and histological features. Interestingly, this patient also exhibited a pseudoisomorphic Köebner response. Although an infective aetiology of viral origin has been suggested for this localized eruption, the aetiology remains unknown. We are of the opinion that the pseudoisomorphic Köebner response in this patient may support the inoculation hypothesis in the pathogenesis of this disorder. [source]
