O91.111
Abscess of breast associated with pregnancy, first trimester
Clinical Classification Guidelines
Medical Intelligence & Overview
An abscess of the breast during pregnancy, particularly in the first trimester, is a localized infection that results in a pocket of pus forming within the breast tissue. This condition is a serious medical concern requiring prompt diagnosis and management to prevent complications for both the mother and the developing baby. Although rare, it can cause significant discomfort and impact the health of the mother during a critical period of pregnancy.
Causes & Symptoms
Clinical Causes: Bacterial infections, often caused by Staphylococcus or Streptococcus bacteria, entering through cracked or injured skin of the breast or nipple. Difficulty breastfeeding or nipple trauma, which may facilitate bacterial entry. Poor breast hygiene or skin conditions leading to increased vulnerability to infection. Underlying infections or areas of skin damage that can serve as entry points for bacteria. Immune system changes during pregnancy that can make infections more likely.
Key Symptoms: Localized swelling and tenderness in one area of the breast. Redness and warmth over the infected area. Presence of a palpable lump or abscess, which may be tender or firm. Pain or discomfort that may worsen with touch or movement. Possible fever or chills if the infection becomes systemic. Drainage of pus from the nipple or through a wound in the skin. General feeling of illness, fatigue, or malaise.
Diagnostic & Treatment
Diagnosis Path: An initial physical exam to assess the size, location, and characteristics of the lump and surrounding tissue. Imaging studies such as ultrasound are often used to confirm the presence of a fluid-filled abscess and evaluate its extent. In some cases, a sample of pus may be collected via aspiration for microbiological analysis to identify the causative bacteria, guiding appropriate treatment.
Treatment Protocols: - Antibiotic therapy tailored to the bacterial infection, chosen carefully to be safe during pregnancy. - Drainage of the abscess, often performed through a small incision or needle aspiration to remove pus and reduce pressure. - Adequate pain management and supportive care. - Encouragement to continue breastfeeding if safe and feasible, as it helps drain the milk and reduce blockage. - Regular follow-up to monitor healing and prevent recurrence. In some cases, hospitalization may be necessary if the infection is severe or complications develop. Surgical intervention is considered if the abscess does not respond to initial treatments or if there are recurrent infections.
