Study Notes
Acute Mastitis and Related Conditions
- Common bacterial species invading breast tissue in acute mastitis include Staphylococcus aureus.
- Acute mastitis symptoms often include breast tenderness, swelling, and warmth.
- Acute mastitis typically occurs in lactating women, especially in the early weeks postpartum.
- Periductal mastitis presents with nipple discharge, pain, and a palpable mass near the nipple.
- Primary risk factor for periductal mastitis is smoking, which increases susceptibility.
- A key characteristic of the pathology of acute mastitis features marked inflammatory infiltrates and ductal obstruction.
- Mammary duct ectasia is identified by dilation of ducts, thickened secretions, and surrounding chronic inflammation.
Malignancies and Tumors
- Breast cancer is the most common malignancy in women.
- Key histological feature of mammary duct ectasia is the presence of dilated ducts filled with thick, sticky secretions.
- Fibrosis in the breast is characterized by dense collagen deposition and stromal changes.
- Osteoblastoma involves a well-circumscribed mass of hemorrhagic, gritty tan tissue comprised of woven bone and surrounding osteoblasts.
- Osteosarcoma predominantly affects adolescents and young adults, typically in the second decade of life.
- Most common benign bone tumor is an osteochondroma.
- Chondromas exhibit a gross morphology of well-defined, hard, firm lesions with a translucent appearance.
- Chondrosarcoma usually affects adults in their 40s and 50s, with peak incidence in middle age.
Osteoid Osteoma and Osteoblastoma
- Osteoid osteomas typically present with nocturnal pain relieved by nonsteroidal anti-inflammatory drugs (NSAIDs).
- Characteristic feature seen in the stroma of osteoblastoma and osteoid osteoma is the presence of prominent vascularity and a dense osteoid matrix.
- Benign tumors with similar histologic features but differing in size and symptoms are termed "benign bone tumors."
- Osteosarcomas commonly arise in metaphysis of long bones, notably around the knee.
General Notes on Bone Neoplasia
- Genetic alterations, particularly in TP53 and RB1, contribute to the development of many bone tumors.
- Osteoid osteomas generally occur in younger individuals, most commonly in teenagers.
- Risk factors for bone neoplasia include prior radiation exposure and certain genetic syndromes.
