Aseptic Abscess Syndrome with Severe Skin Involvement: Case Report

Aseptic pyomyositis in rheumatoid arthritis treated with corticosteroid and DMARDs

Pyomyositis is a purulent infection of skeletal muscle that is mostly observed in tropical countries. Aseptic pyomyositis is a rare, potentially life-threatening disorder characterized by the formation of sterile pus in muscle. We present a case of 53-years old female, diagnosed case of seropositive rheumatoid arthritis, presented with pain and swelling of the right calf muscle for 2 weeks. There was no history of fever, cough, skin erythema, no history of prolonged standing or immobility, or fetal loss. The diagnosis was made as rheumatoid arthritis with autoimmune pyomyositis, and the patient was treated with oral prednisolone 1mg/kg body weight in tapering dose, cs DMARDS, (methotrexate 25 mg once a week, and leflunomide 20mg daily hydroxychloroquine 200 mg daily orally) and another supportive treatment along with surgical drainage of pus was done. There was complete resolution of the initial lesion and remission of the primary disease in 3 months.

Characterization and Management of Amicrobial Pustulosis of the Folds, Aseptic Abscess Syndrome, Behçet Disease, Neutrophilic Eccrine Hidradenitis, and Pyostomatitis Vegetans-Pyodermatitis Vegetans

Neutrophilic dermatoses are a broadly heterogeneous group of inflammatory skin disorders. This article reviews 5 conditions: amicrobial pustulosis of the folds, aseptic abscess syndrome, Behçet disease, neutrophilic eccrine hidradenitis, and pyostomatitis vegetans-pyodermatitis vegetans.The authors include up-to-date information about their epidemiology, pathogenesis, clinicopathologic features, diagnosis, and management.

Aseptic nasal septal abscess in patients with ulcerative colitis: two case reports. Case report

Ulcerative colitis (UC) may be associated with different extra-intestinal manifestations (EIM), which are often difficult to diagnose and treat, and may complicate the course of the disease. EIM are a multidisciplinary problem encountered by doctors of various specializations. However, many incidences of EIM in patients with UC remain unknown. The coexistence of UC and aseptic nasal abscess (ANA) is uncommon. Here, we describe two cases of ANA in young female patients with UC. ANA run in parallel with intestinal disease activity and led to necrosis of the septal cartilage. Moreover, pyoderma gangrenosum was described in one of them. Aseptic abscess syndrome should be kept in mind when a microbial factor is not identified, the diagnosis is not clear or a patient is not improving on appropriate antibacterial therapy. ANA can present as a rare complication of UC.

Aseptic abscess in the abdominal wall accompanied by monoclonal gammopathy simulating the local recurrence of rectal cancer: A case report

BACKGROUND

Infectious abscesses in the abdominal wall can be secondary to retained foreign bodies (e.g., stones, use of artificial mesh, use of silk yarn in surgical suture), inflammatory diseases (e.g., acute appendicitis), and perforated malignancies of the digestive tract (particularly the colon). Aseptic abscesses (AAs) are relatively rare. To the best of our knowledge, this is the first report of an AA in the abdominal wall accompanied by monoclonal gammopathy of undetermined significance (MGUS) at 5 years after laparoscopic proctectomy.

CASE SUMMARY

A 72-year-old female patient presented with an enlarged painless mass in the lower abdomen for 1 year. She had a history of obesity, diabetes, and MGUS. Her surgical history was laparoscopic resection for rectal cancer 6 years prior, followed by chemotherapy. She was afebrile. Abdominal examination revealed a smooth abdomen with a clinically palpable solid mass under a laparotomy scar in the left lower quadrant. No obvious tenderness or skin redness was spotted. Laboratory data were not remarkable. Computed tomography scan revealed a low-density mass of 4.8 cm in diameter in the lower abdominal wall, which showed high uptake on positron emission tomography. The preoperative diagnosis was an abscess or tumor, and surgical resection was recommended. The mass was confirmed to be an AA by microbiological and pathological examinations. The patient recovered well after surgery. There was no evidence of recurrence 2 years later.

CONCLUSION

It is important to consider underlying conditions (diabetes, chemotherapy, MGUS) which may contribute to AA formation in the surgical wound.
