Atypical mycobacteriosis

Andrés Tirado-Sánchez, Alexandro Bonifaz
Nodular lymphangitis, also known as sporotrichoid lymphocutaneous infections, is characterized by suppurative inflammatory nodules along the lymphatic vessels. This manifestation is classic of sporotrichosis, however, other infections such as nocardiosis, atypical mycobacteriosis, leishmaniasis, among others, can also express this clinical pattern. Sporotrichosis, which often occurs in gardeners, remains the most recognized cause of nodular lymphangitis. The histopathological studies, as well as the culture are diagnostic standards of lesions that do not respond to empirical treatment...

Tuberculosis is a serious disease of humans and animals, caused by bacteria of the Mycobacterium genus. This leads to complications in the life of the sick person, and subsequently to death. The cattle, who have been diagnosed with this bacterium, are usually sent to the slaughter, with the result that their livestock is reduced. Mycobacteriosis is also a disease, after determining which cattle are most often sent to slaughter. Such a reduction in livestock numbers has a negative effect on the economy. Of the 300 samples from the animals, 25 cultures of atypical bacteria responding to tuberculin were isolated...

Introduction. Mycobacterium marinum is a non-tubercular mycobacterium residing in fresh or salt water (in tropical or temperate areas); it is a fish and human pathogen, and in immunocompromised patients can cause severe cutaneous and subcutaneous infections. Case presentation. A 46-year-old white man who underwent immunosuppressive therapy was admitted to our department in May 2016 for skin lesions previously diagnosed as 'unusual erysipelas'. We rejected the hypothesis of erysipelas, due to the clinical features, and our diagnostic hypotheses were oriented towards sporotrichosis, atypical mycobacteriosis, cutaneous tuberculosis and cutaneous sarcoidosis...

Pelvic tuberculosis is a type of extrapulmonary tuberculosis. The disease is accompanied by clinical and laboratory findings which may be unspecific and present aspects of other diseases, including gynecological malignancies. In this report, the authors presented a case of pelvic tuberculosis associated with peritoneal tuberculosis in a young woman exhibiting imaging and tumor markers consistent with ovarian neoplasm. An intraoperative frozen section analysis detected atypical cells that were suggestive of ovarian borderline or malignant epithelial neoplasia...

BACKGROUND: The poor treatment outcomes of multidrug-resistant tuberculosis (TB) and the emergence of extensively drug-resistant TB and extremely and totally drug-resistant TB highlight the urgent need for new antituberculous drugs and other adjuvant treatment approaches. OBJECTIVES: We have treated cavitary tuberculosis by the application of endobronchial one-way valves (Zephyr®; Pulmonx Inc., Redwood City, Calif., USA) to induce lobar volume reduction as an adjunct to drug treatment...

The incidence of retro-parapharyngeal localization of cervical adenitis due to non-tuberculous mycobacteria is very rare. We present a case of an 18-months-old child with an involvement of parapharyngeal and retropharyngeal areas, right parotid and submandibular regions by atypical mycobacteriosis in the CT and MRI scan. The masses were surgically removed and the frozen-section histological exam upheld their atypical mycobacterial origin.

INTRODUCTION: The incidence of atypical mycobacterial infection in Europe is estimated at one case per 100,000 persons/year. Despite the low incidence of Mycobacterium avium infection, it can result in a nodular lesion simulating lung cancer. We report a case of atypical mycobacteriosis, mimicking lung cancer, which led to a lobectomy. CASE REPORT: It was a right pulmonary upper lobe nodule found in a 63-year-old COPD patient, partially nephrectomized for renal carcinoma, and weekly treated by methotrexate for rheumatoid arthritis...

BACKGROUND: Association of leukoencephalopathy and atypical mycobacteriosis has been rarely reported. We present a case that is relevant for its unusual presentation and because it may shed further light on the pathogenic mechanisms underlying reversible encephalopathies. CASE REPORT: We report the case of a Hispanic 64-year-old woman with cognitive decline and extensive leukoencephalopathy. Magnetic resonance imaging revealed white-matter lesions with increased water diffusivity, without blood-brain-barrier disruption...

Atypical mycobacteria are saprophytic organisms not transmitted from person to person, which affect mainly immunosuppressed but also immunocompetent individuals. We present a case of atypical mycobacteriosis after a vascular procedure, with widespread cutaneous lesions associated with polyarthralgia. Mycobacterium chelonae was identified by the polymerase chain reaction (PCR) method. The patient showed improvement after treatment with three antibiotics. Mycobacterium chelonae causes skin lesions after invasive procedures...

Here we present a case series from a primate research facility. The index case, a 4-year-old pig-tailed macaque (Macaca nemestrina) experimentally infected with chimeric simian-human immunodeficiency virus (SHIVSF162 P4), developed weight loss and was euthanized. Based on necropsy results the animal was diagnosed with opportunistic atypical mycobacteriosis associated with simian AIDS (SAIDS). Subsequently, tissues from the index animal, as well as tissues and oral mucosal swabs from six SHIV-infected contacts, were analyzed using molecular methods and found to contain nucleic acid sequences characteristic of Mycobacterium tuberculosis complex (MTBC)...

OBJECTIVES: Atypical familial mycobacteriosis (AFM, OMIM #209950) is caused by mutations in genes regulating IL12/IFNG pathway. Some of the mutations exhibit incomplete penetrance, and they have been proposed to be involved in the common (polygenic) predisposition to tuberculosis (TB). We set out to test this hypothesis in two populations from Siberian region of Russia with high prevalence of TB. MATERIAL AND METHODS: The prevalence of twelve mutations in IL12/IFNG pathway genes of were analysed in 331 Russians and 238 Tuvinians TB patients and in 279 healthy Russians and 265 healthy Tuvinians...

Atypical mycobacteriosis (AM) is a rare disease, which is caused by an infection with mycobacteria other than tuberculosis (MOTT). In children, the cervical lymph nodes are frequently affected. MOTT are a pathogen or facultative pathogen environmental germs, which can affect otherwise healthy individuals. The diagnostic and therapeutic management is often challenging. Currently, there are only few data published about the systematic investigation and therapy of children with AM. In a retrospective study, 29 children with AM were evaluated...

Infection with atypical mycobacteria (MAC) is a well-known complication of AIDS that typically occurs only in people with advanced immunodeficiency. We studied tissues from 13 patients with HIV and atypical mycobacterial infection who died in St Petersburg Russia from 2009-2012. Three patterns of disease were identified that suggest effects of host resistance. The first pattern was in people paucibacillary disease. They had positive blood cultures and histologic changes consistent with mycobacterial infection, but no stainable acid fast bacilli (AFB)...

Atypical mycobacteriosis is a rare cause of cervical lymphadenitis that most frequently affects immunoincompetent children between the ages of 12 months and 5 years. The typical clinical manifestation is a painless unilateral cervical mass. The nonspecific clinical symptoms and laboratory parameters complicate diagnosis and, therefore, therapeutic management. Various therapeutic options, including surgery, antimycobacterial drug therapy and wait-and-scan approaches are discussed in the literature. Complete surgical excision has become the established treatment of choice...

BACKGROUND: While pulmonary aspiration syndrome (PAS) is primarily clinically diagnosed, atypical PAS cases can be misdiagnosed clinically and are more accurately diagnosed histologically. To elucidate clinicopathological features of these rare cases, we examined PAS cases determined by histological examination of transbronchial lung biopsy (TBLB) specimens. METHODS: Of 6105 TBLB cases investigated from 1990 to 2007, 11 were diagnosed as PAS based on histology. Of these, we examined 9 records in detail, as the medical records for 2 cases were unavailable...

Abstract We report two cases of rheumatoid arthritis (RA) with atypical mycobacteriosis. Opportunistic infections are critical complications for rheumatic diseases. The use of steroids or immunosuppressants may increase the risk of opportunistic infections. However, these reports are rare in that they demonstrate atypical mycobacterial infections as complications of RA, even though no immunosuppressive agents were used. We discuss the characteristics of atypical mycobacterial infections of the lung in RA.
