Mycobacterium porcinum Infection of Hilar and Mediastinal Lymph Nodes: A Case Report and Literature Review

In the available reports on clinical medicine, the infection sites of Mycobacterium porcinum include wounds, bone marrow, respiratory tract, and catheters. A 61-year-old woman was admitted to our hospital; her hilar and mediastinal lymph nodes were found to be enlarged during health examination, but there was no specific discomfort. Initially, she had undergone a mediastinal lymph node biopsy and pathology, but the diagnosis was not confirmed. However, 16S rRNA gene sequencing revealed M. porcinum infection of hilar and mediastinal lymph nodes. Subsequently, she was treated with clarithromycin, amikacin, imipenem, and tigecycline. After 2 months, chest computed tomography showed a significant reduction in lymph nodes. M. porcinum infection was considered to be the cause of disease.

Use of a Cervicofacial Flap in Closing Large Defects Following Wide Local Excision of Complicated Preauricular Lesions

PURPOSE

To describe innovative surgical technique for closure of large defect following complicated preauricular cyst excision secondary to prior failed excision attempts, infections, and drainage procedures. Preauricular cysts must be widely excised including any fistulous tracts in order to reduce recurrence rates; however, the resultant large local excision poses cosmetic challenges.

METHODS

Retrospective chart review of 3 patient cases who underwent excision of recurrent preauricular lesions involving cervical parotid flap closure. All three cases demonstrate complicated preauricular congenital cysts which were infected and had prior drainage, excision attempts, or sclerotherapy. A cervicoparotid flap was used to close all defects cosmetically with no facial nerve weakness and without distortion to the oral commissure or lateral canthus.

RESULTS/CONCLUSIONS

There is a high recurrence rate seen with wide local congenital cyst excisions that have been previously excised, infected, and drained; as well as, cosmetically unfavorable outcomes utilizing traditional repair. Utilizing our closure technique which involves reconstructive local regional flap with cervicoparotid approach our 3 patients have had no reoccurance of cyst or infection. Our approach also maximizes cosmetic outcomes, with reduced scar visibility. Pre and postoperative photos will be shown.
