“…Subramanian et al (9) report 18 additional cases diagnosed in India. Review of the literature revealed 51 more cases in India, 3 probable cases, 1 unpublished case mentioned in a review, and 2 cases from personal communications (13–48). Thirteen cases have been diagnosed in the United Kingdom in patients with prior residence on the Indian subcontinent (10), and 1 case was diagnosed in Canada in a patient who had recently traveled to India (49).…”

Histoplasmosis is recognized to occur in the Ohio and Mississippi River Valleys of the United States, but less widely appreciated is its worldwide distribution. We report a case of disseminated histoplasmosis with disease involving skin, lungs, and epiglottis in a renal transplant patient 6 months after a trip to Bangladesh, to highlight the potential risk of acquisition of this infection in the Indian subcontinent.

“…Infection is most commonly asymptomatic, but pneumonitis or dissemination may occur. Case reports of myositis exist in the literature, including a case of nodular myositis in an AIDS patient (89). Other cases presented as fulminant necrotizing myofascial infections, which occurred in a transplant recipient and a patient with a rheumatologic condition on immunosuppressive agents (241,243).…”

SUMMARY Infectious myositis may be caused by a broad range of bacterial, fungal, parasitic, and viral agents. Infectious myositis is overall uncommon given the relative resistance of the musculature to infection. For example, inciting events, including trauma, surgery, or the presence of foreign bodies or devitalized tissue, are often present in cases of bacterial myositis. Bacterial causes are categorized by clinical presentation, anatomic location, and causative organisms into the categories of pyomyositis, psoas abscess, Staphylococcus aureus myositis, group A streptococcal necrotizing myositis, group B streptococcal myositis, clostridial gas gangrene, and nonclostridial myositis. Fungal myositis is rare and usually occurs among immunocompromised hosts. Parasitic myositis is most commonly a result of trichinosis or cystericercosis, but other protozoa or helminths may be involved. A parasitic cause of myositis is suggested by the travel history and presence of eosinophilia. Viruses may cause diffuse muscle involvement with clinical manifestations, such as benign acute myositis (most commonly due to influenza virus), pleurodynia (coxsackievirus B), acute rhabdomyolysis, or an immune-mediated polymyositis. The diagnosis of myositis is suggested by the clinical picture and radiologic imaging, and the etiologic agent is confirmed by microbiologic or serologic testing. Therapy is based on the clinical presentation and the underlying pathogen.

“…It disseminates to the lung, lymph nodes, breast, adrenal glands, spleen, and subcutis particularly in the immunocompromised patient, and classically produces mediastinal lymphadenopathy with calcifications mimicking tuberculosis and carcinoma on chest X-ray. 20,21 It is a dimorphic fungus most commonly seen as a 3-5 lm diameter oval pale yeast with single variable narrow based budding. [1][2][3] It is difficult to see in routine Pap and Giemsa stains, but when plentiful it can be seen as a negative image in the cytoplasm of multinucleated giant cells or much more easily in the GMS (Fig.…”

Role of fine needle aspiration biopsy cytology in the diagnosis of infections

Diagnostic Cytopathology

The role of fine needle aspiration biopsy (FNAB) cytology in diagnosing infections has expanded due to the increase in the number of immune compromised patients and the increasing role of FNAB in the developing world where infection is a major cause of illness. FNAB has become the first procedural test in cases where the clinical and imaging findings suggest an infectious lesion or where there is a differential diagnosis of infection or metastatic or primary tumor. This applies to FNAB of palpable or image directed or deep seated lesions accessed by EUS and EBUS. This article details a recommended approach and technique for FNAB of infectious lesions, and discusses the role of rapid on site evaluation and the application of ancillary testing including the rapidly expanding array of molecular tests based on FNAB material. The utility of recognizing suppurative and granulomatous infectious patterns in FNAB direct smears, and the specific cytomorphological features on routine Papanicolaou and Giemsa stains and on special stains of FNAB smears is described for a large number of bacterial, fungal, viral, parasitic, and protozoan infections. The role of cytopathologists is to now train cytopathologists in sufficient numbers to provide FNAB services, teach trainee cytopathologists and cytotechnologists, and to encourage our clinical colleagues to use FNAB in the diagnosis of infections and other lesions to the benefit of patients and the medical system.
