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. The clinical form depends on the immune state of the host and on the entry points. The diagnosis is based essentially on culture and the mycobacteria is identified by PCR. We highlight the importance of investigating atypical mycobacteriosis when faced with granulomatous lesions associated with a history of invasive procedures.

Infectious complications in peritoneal dialysis (PD) remain a constant challenge, with atypical pathogens posing significant risks. This case from Thailand highlights the rare occurrence of , an often-overlooked non-tuberculous mycobacterium (NTM), as the causative agent in a catheter-related exit-site infection that progressed to peritonitis. Initially misattributed to from preceding exit-site infections, was ultimately identified as the primary pathogen through multiple effluent cultures and advance polymerase chain reaction sequencing.

Shoulder abscesses, commonly resulting from bacterial infections, can occasionally present with atypical etiologies and delayed onset. We report a rare case of a massive polymicrobial shoulder abscess developing two decades after an insect bite, emphasizing its clinical presentation, diagnostic approach, and surgical management. A 65-year-old female presented with severe, progressively worsening right shoulder pain, a 20 cm swelling, and purulent discharge persisting for 15 days.

Clinically uncommon, this condition can involve the entire gastrointestinal tract, often presenting diagnostic challenges in differentiation from Crohn's disease.
Methods: In this case, atypical BD was diagnosed through endoscopic examination, whereas latent tuberculosis infection (LBTI) was confirmed via T-SPOT and PPD tests.

Chronic mesh infections after inguinal hernia repair present significant clinical challenges due to biofilm-mediated resistance, involvement of multidrug-resistant and atypical pathogens, and gaps in preventive strategies. Our case series of four patients highlights critical research gaps, including the overlooked role of atypical pathogens such as , diagnostic challenges in detecting slow-growing or resistant organisms and perioperative sterilisation lapses, especially inconsistent Glutaraldehyde use during late-day operations. Many patients suffered with persistent sinuses and recurrent hernias months after surgery.

Rationale: Synovial sarcoma (SS) is a rare and highly malignant soft tissue sarcoma. When SS occurs in atypical locations, it can present significant diagnostic challenges. We report a case of paraspinal SS initially misdiagnosed as spinal tuberculosis, highlighting the diagnostic difficulties and the importance of considering SS in the differential diagnosis.
