L02.91

Clinical Causes: Bacterial infections, especially Staphylococcus aureus Spread of infection from nearby skin injuries or cuts Ingrown hairs or folliculitis that lead to abscess formation Compromised immune system that facilitates infection Poor hygiene or skin conditions that favor bacterial growth Obstruction of sweat glands or hair follicles

Key Symptoms: A painful, swollen lump in the skin that may be warm to the touch Redness around the affected area Possible presence of pus or tenderness upon touching Fever and chills if the infection spreads or becomes severe Localized skin warmth and increased sensitivity Overlying skin may appear shiny or stretched In some cases, the abscess may drain spontaneously or require drainage

Diagnosis Path: Diagnosing a cutaneous abscess typically involves clinical examination by a healthcare professional, who will assess the appearance, size, and tenderness of the lump. In certain cases, additional tests such as ultrasound imaging or laboratory analysis of pus samples may be performed to confirm the presence of infection and identify the causative bacteria. These diagnostic steps help determine the most appropriate treatment plan and exclude other skin conditions that may mimic abscesses.

Treatment Protocols: Treatment for a cutaneous abscess depends on its size, severity, and location. Common approaches include: - Drainage: the primary treatment involves surgically draining the pus to relieve pressure and remove infectious material. - Antibiotics: prescribed if there is surrounding cellulitis, multiple abscesses, or if the patient has underlying health issues that impair healing. - Care at home: maintaining good hygiene, applying warm compresses to promote drainage, and keeping the area clean. - Follow-up: monitoring the site for signs of ongoing infection or recurrence. In cases where the abscess is small and skin-opening has occurred naturally, minimal intervention may be necessary. However, larger or more complex abscesses generally require medical intervention to prevent complications.
