Scalp actinomycosis mimicking soft tissue mass

Area of Science:

• Infectious Diseases
• Microbiology
• Dermatology

Background:

• Actinomycosis is a rare bacterial infection caused by Actinomyces species.
• These bacteria are typically found in the human oral cavity, gastrointestinal, and female genital tracts.
• Commonly reported cases involve cervicofacial or oral regions.

Observation:

• This report details a rare case of subcutaneous actinomycosis.
• The infection was localized to the upper posterior neck and involved the scalp.
• Clinical presentation included swelling, suppuration, fibrosis, and draining sinuses.

Findings:

• The case demonstrates a less common presentation of actinomycosis.
• Subcutaneous involvement of the neck and scalp by Actinomyces is unusual.
• The diagnosis was confirmed based on clinical and microbiological findings.

Implications:

• This case broadens the understanding of actinomycosis's clinical spectrum.
• It emphasizes the importance of considering actinomycosis in deep neck and scalp infections.
• Further research into rare presentations can improve diagnostic accuracy and patient outcomes.
