“…MTB of subcutaneous tissue may arise by direct extension from adjacent inflamed areas, usually lymph nodes, bone, or pleura [17]. However, its pathogenesis is uncertain, and it may result from the hematogenous dissemination of pulmonary TB, contiguous infection from an underlying structure, direct traumatic inoculation, or an altered immune status [18]. On the other hand, musculoskeletal NTM infections are acquired by direct exposure to contaminated water sources following accidental trauma, penetrating injury, cosmetic or minor surgical procedures, percutaneous catheterization, or contaminated injection in immunocompetent patients [19,20].…”

Erythema nodosum (EN) is an immunologic reaction to various stimuli, and characterized by inflammation of subcutaneous fat cells, resulting in tender red nodules and lumps. Mycobacterial infection is sometimes associated with its development. According to previous reports, the most common form of EN involves thickening of the superficial fascia of the cutaneous or subcutaneous fat layer. However, the two cases described here had a subcutaneous nodule in magnetic resonance images. Although in many cases, EN is idiopathic, treatment for a causative disease is needed when EN manifests in the presence of a specific disease. Therefore, if subcutaneous nodule or mass is diagnosed as EN histopathologically, underlying disease should be investigated to ensure appropriate treatment. Here, we report two cases of Mycobacterium tuberculosis or a nontuberculous Mycobacterial infection pathologically presented as EN and describe the MRI findings of subcutaneous Mycobacterial infection.

BACKGROUND Soft tissue tuberculosis is rare and insidious, with most patients presenting with a localized enlarged mass or swelling, which may be factors associated with delayed diagnosis and treatment. In recent years, next-generation sequencing has rapidly evolved and has been successfully applied to numerous areas of basic and clinical research. A literature search revealed that the use of next-generation sequencing in the diagnosis of soft tissue tuberculosis has been rarely reported. CASE SUMMARY A 44-year-old man presented with recurrent swelling and ulcers on the left thigh. Magnetic resonance imaging suggested a soft tissue abscess. The lesion was surgically removed and tissue biopsy and culture were performed; however, no organism growth was detected. Finally, Mycobacterium tuberculosis was confirmed as the pathogen responsible for infection through next-generation sequencing analysis of the surgical specimen. The patient received a standardized anti-tuberculosis treatment and showed clinical improvement. We also performed a literature review on soft tissue tuberculosis using studies published in the past 10 years. CONCLUSION This case highlights the importance of next-generation sequencing for the early diagnosis of soft tissue tuberculosis, which can provide guidance for clinical treatment and improve prognosis.

Metastatic Tuberculous Chest Wall and Massive Psoas Abscesses in an Immunocompetent Patient

Extrapulmonary tuberculosis (TB) is rare in immunocompetent healthy adults. TB of the chest wall accounts for 1%–5% of all cases of musculoskeletal TB. Psoas abscess can be either primary or secondary to diseases like Pott's spine. We describe a patient with massive lower chest wall abscess extending to abdominal muscles and an asymptomatic large psoas abscess detected on imaging due to spine TB which responded well to antitubercular therapy and drainage without surgical measures. The concomitant presence of a massive chest wall abscess and psoas abscess due to TB in an immunocompetent patient was not reported previously.
