is a ubiquitous organism classified as a nontuberculous mycobacterium that rarely causes indolent skin or soft-tissue infections, especially in immunocompromised patients. Given the rarity of infection, diagnosis can be difficult because cutaneous lesions may be considered a worsening of the underlying disease or a benign condition. Here, we report a case of a rapidly progressing cutaneous infection in a patient with nephrotic syndrome.

Background: Diseases caused by (MTB) and non-tuberculous mycobacteria (NTM) have similar clinical symptoms but require different treatments. Rapid and accurate identification of MTB and NTM is essential for proper patient management and treatment.
Methods: To develop and assess a multiplex real-time fluorescence PCR (Multiplex PCR) method for rapid identification of MTB, complex (MAC), M.

is a rapidly growing nontuberculous mycobacterium (NTM) that is ubiquitous in the environment and is associated with skin and soft tissue infections (1). Because is an opportunistic infection, it can present as skin abscess, cellulitis, osteomyelitis, pulmonary infection or disseminated infections, particularly in individuals with compromised immune systems or underlying lung conditions such as cystic fibrosis or bronchiectasis. is one of the most pathogenic rapidly growing mycobacteria (RGM).

Objectives: Nontuberculous mycobacteria (NTM) are increasingly recognized opportunistic pathogens found ubiquitously in the environment. The presence of multiple NTM species at the site of disease complicates diagnosis and treatment.
Case And Management: A 40-year-old patient who tested positive for HIV, with an absolute clusters of differentiation 4+ T-cell count of 3 cells/µl and cryptococcaemia, presented with hemoptysis, productive cough, and weight loss.
