Primary Cutaneous Nocardiosis: a Case Study and Review
Study Primary cutaneous nocardiosis: A case study and review Arun C. Inamadar, Aparna Palit Department of Dermatology, Venereology & Leprosy, BLDEA’s SBMP Medical College, Hospital & Research Centre, Bijapur, India. Address for correspondence: Dr. Arun C. Inamadar, Professor & Head, Department of Dermatology, Venereology & Leprosy, BLDEA’s SBMP Medical College, Hospital & Research Centre, Bijapur - 586103, India. E-mail: [email protected]. ABSTRACT Background: Primary cutaneous nocardiosis is an uncommon entity. It usually occurs among immunocompetent but occupationally predisposed individuals. Aim: To study clinical profile of patients with primary cutaneous nocardiosis in a tertiary care hospital and to review the literature. Methods: The records of 10 cases of primary cutaneous nocardiosis were analyzed for clinical pattern, site of involvement with cultural study and response to treatment. Results: All the patients were agricultural workers (nine male) except one housewife. The commonest clinical type was mycetoma. Unusual sites like the scalp and back were involved in two cases. Culture was positive in six cases with N. brasiliensis being commonest organism. N. nova which was previously unreported cause of lymphocutaneous nocardiosis, was noted in one patient, who had associated HIV infection. All the patients responded to cotrimaxazole. Conclusion: Mycetoma is the commonest form of primary cutaneous nocardiosis and responds well to cotrimoxazole. KEY WORDS: Primary cutaneous nocardiosis, Mycetoma, Lymphocutaneous nocardiosis INTRODUCTION infection is prevalent. Many of the large series on nocardial infections mention the incidence of Cutaneous nocardiosis presents either as a part of cutaneous nocardiosis without specifying whether the disseminated infection or as a primary infection infection is primary or secondary.

Open Access Case Report DOI: 10.7759/cureus.5294 Disseminated Nocardiosis: A Case Report Ines M. Leite 1 , Frederico Trigueiros 1 , André M. Martins 1 , Marina Fonseca 1 , Tiago Marques 2 1. Serviço De Medicina 2, Hospital De Santa Maria, Lisboa, PRT 2. Serviço De Doenças Infecciosas, Hospital De Santa Maria, Lisboa, PRT Corresponding author: Ines M. Leite, [email protected] Abstract Disseminated nocardiosis is a rare infection associated with underlying immunosuppression, and patients usually have some identifiable risk factor affecting cellular immunity. Due to advances in taxonomy and microbiology identification methods, infections by Nocardia species are more frequent, making the discussion of its approach and choice of antibiotherapy increasingly relevant. A 77-year-old man presented to the emergency department with marked pain on the right lower limb, weakness, and upper leg edema. He had been diagnosed with organized cryptogenic pneumonia one year before and was chronically immunosuppressed with methylprednisolone 32 mg/day. Blood cultures isolated Nocardia cyriacigeorgica. Computed tomography revealed a gas collection in the region of the right iliacus muscle with involvement of the gluteal and obturator muscles upwardly and on the supragenicular plane inferiorly. Triple therapy with imipenem, amikacin, and cotrimoxazole was started, and the patient was submitted for emergent surgical decompression, fasciotomy, and drainage due to acute compartment syndrome. The patient had a good outcome and was discharged from the hospital after 30 days of intravenous therapy. This case illustrates the severity of Nocardia infection and highlights the need for a meticulous approach in the diagnosis and treatment of these patients. Categories: Internal Medicine, Infectious Disease Keywords: nocardia, nocardia infection, immunosuppression Introduction In the suborder of Corynebacterineae, three genera have strains that may be pathological to humans, with some characteristics similar to Fungi: Mycobacterium, Corynebacterium, and Nocardia.

Acquired most often by inhalation and less commonly by percutaneous inoculation, subsequent hematogenous dissemination may lead to infection of almost any organ, with a particular predilection for the central nervous system. Nocardial brain abscesses are rare. To the best of our knowledge, pediatric Nocardial brain abscesses have not been documented in Human Immunodeficiency Virus (HIV)-infected children in the English-language literature, to date. In reporting two Nocardial brain abscesses in a 9 year old AIDS patient with intermittent seizures, we highlight the difficulty associated with the ante-mortem diagnosis of Nocardial brain abscesses, and the need for cognizance of rare entities occurring in HIV-infected children. Furthermore, we emphasize the pivotal role of the autopsy in finalizing the nature of the cerebral pathology, the cause of the seizures albeit post-mortem, a cause of death and in providing a platform for continued learning in the AIDS era.

A case report and literature review Wo Yao1, Jing Xue2 Departments of 1Allergy, 2Rheumatology, Second Affiliated Hospital, School of Medicine, Zhejiang University, Hangzhou, P.R. China Received December 13, 2018; Accepted April 9, 2019; Epub June 15, 2019; Published June 30, 2019 Abstract: Immunocompromised patients are at high risk of Nocardia, however infection in these patients can also mimic relapsed or refractory autoimmune disease and that make diagnosis difficult. Herein is described a 60-year- old male diagnosed with anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) who presented with fever, short of breath, cough, headache, and a subcutaneous mass in his right forearm after 3 months therapy with full-dose oral corticosteroid and intravenous cyclophosphamide. Given that the currently available laboratory tests and associated imaging features are nonspecific, it was quite difficult to differentiate between a recurrence of the patient’s AVV and infection as a complication. The patient was finally diagnosed with systemic nocardiosis base on a subcutaneous abscess puncture fluid culture after 3 weeks of hospitalization. Trimethoprim-sulfamethoxazole (TMP-SMX) was administered while the steroid was tapered, after which the patient’s systemic manifestations grad- ually resolved. A literature review identified 24 cases of nocardiosis as a complication of systemic vasculitis was performed. Male patients with systemic vasculitis (especially AAV or Behcet’s disease) aged ≥ 60 years who were treated with corticosteroid in conjunction with or without immunosuppressant therapy were at high risk of Nocardia infection.
