B43.2
Subcutaneous pheomycotic abscess and cyst
Clinical Classification Guidelines
Medical Intelligence & Overview
Subcutaneous pheomycotic abscess and cyst, coded as ICD-10 B43.2, refers to a type of skin infection characterized by the formation of abscesses and cysts filled with pus and other infectious material beneath the skin. This condition typically arises from fungal infections affecting subcutaneous tissues, leading to localized swelling, pain, and potential skin changes. Recognizing the signs and understanding the nature of this condition can aid in effective management and treatment, although specific medical advice should always be sought from healthcare professionals.
Causes & Symptoms
Clinical Causes: Infections caused by specific fungi, notably those from the Phaeoacremonium or related fungal species Contamination through traumatic skin injuries, such as cuts or punctures, allowing fungi to invade subcutaneous tissues Immunosuppressed states, which can increase susceptibility to fungal infections Exposure to environments conducive to fungal growth, such as soil, decaying plant matter, or contaminated water Poor hygiene practices that facilitate fungal contamination of skin wounds
Key Symptoms: Swelling or lump under the skin that may be tender or painful Presence of pus or thick, discolored fluid within cysts or abscesses Redness and warmth over the affected area Skin changes such as ulceration or breaking over the cyst or abscess Fever or general malaise in more widespread or severe cases Slow-growing lesions that may persist or recur over time
Diagnostic & Treatment
Diagnosis Path: Physical assessment to evaluate the size, location, and characteristics of the lesion Imaging tests such as ultrasound or MRI to assess the extent of the abscess or cyst Collection of pus or tissue samples for laboratory analysis to identify the fungal species involved Histopathological examination to confirm fungal infection and differentiate from other skin conditions Additional blood tests may be conducted to assess overall health and immune status
Treatment Protocols: Antifungal medications, tailored to the specific fungal pathogen identified through laboratory testing Surgical drainage of abscesses to remove accumulated pus and reduce pressure Removal or excision of persistent cysts that do not respond to medication Supportive care such as pain management and wound care to promote healing Monitoring for signs of recurrence or spread of infection
