S93 Sebaceous cyst (ICD-10:L72.3)

Introduction

Sebaceous cysts are noncancerous, closed sacs or cysts that develop within the skin. They are typically filled with a yellowish, oily substance called sebum.^[1] Sebaceous cysts are common and can occur anywhere on the body, but they most commonly appear on the face, neck, and trunk.^[2] The aim of this guide is to provide a comprehensive overview of the symptoms, causes, diagnostic steps, possible interventions, and lifestyle interventions for sebaceous cysts.

Codes

• ICPC-2 Code: S93 Sebaceous cyst
• ICD-10 Code: L72.3 Sebaceous cyst

Symptoms

• Visible bump or lump on the skin^[3]
• Skin-colored or slightly yellowish appearance^[4]
• Smooth and round in shape^[5]
• May be firm or soft to the touch^[6]
• May be tender or painful if infected^[7]
• May have a central opening or punctum^[8]

Causes

• Blockage or damage to a hair follicle or sebaceous gland^[9]
• Hormonal changes^[10]
• Genetic predisposition
• Trauma to the skin

Diagnostic Steps

Medical History

• Gather information about the patient’s symptoms, including the appearance, size, and location of the cyst.
• Ask about any previous cysts or skin conditions.
• Inquire about any recent trauma or injury to the affected area.
• Assess the patient’s medical history for any underlying conditions that may contribute to the development of sebaceous cysts.

Physical Examination

• Inspect the cyst visually, noting its size, shape, color, and any signs of inflammation or infection.
• Palpate the cyst to assess its texture, consistency, and tenderness.
• Check for any signs of drainage or discharge from the cyst.
• Examine the surrounding skin for any signs of infection or inflammation.

Determine Severity

• Classify the sebaceous cyst based on severity and depth:
  • Superficial cyst: Located near the surface of the skin and easily visible.
  • Deep cyst: Located deeper within the skin layers and may require further evaluation or imaging.

Laboratory Tests

• No specific laboratory tests are typically required for the diagnosis of sebaceous cysts.
• In cases of suspected infection, a wound culture may be performed to identify the causative bacteria.

Diagnostic Imaging

• Diagnostic imaging is generally not necessary for the diagnosis of sebaceous cysts.
• However, in cases where the cyst is deep or there is suspicion of an underlying mass, imaging modalities such as ultrasound or MRI may be used to visualize and assess the cyst.

Other Tests

• Other diagnostic tests are usually not required for the diagnosis of sebaceous cysts.
• However, if there is suspicion of an underlying mass or malignancy, a biopsy may be performed to rule out other conditions.

Follow-up and Patient Education

• Advise the patient to monitor the cyst for any changes in size, shape, or symptoms.
• Instruct the patient on proper wound care and hygiene to prevent infection.
• Provide information on when to seek medical attention if the cyst becomes painful, inflamed, or shows signs of infection.
