Cystic tumors and cysts
Cystic tumors and cysts are benign lesions, mostly congenital. Cystic tumors and cysts can occur in many organs, causing various diseases. The most common examples include liver cysts, kidney cysts, and simple ovarian chocolate cysts. Sometimes, multiple cysts can develop in a single organ, such as in polycystic kidney disease.
View detailsChronic lymphadenitis
Chronic lymphadenitis, also known as hyperplastic lymphadenitis, is characterized by significant cellular proliferation within lymph nodes due to repeated or persistent action of a pathogenic microorganism. It primarily manifests as enlarged, painful, and recurrently swollen lymph nodes, with or without fever.
View detailsCecal cancer
Cecal cancer refers to the cancerous transformation of tissues in the appendix region, from the end of the small intestine to the beginning of the ascending colon, and is a specific type of colorectal cancer. The vast majority of patients are over 40 years old, with about 15% being under 30. It is more common in males.
Appendiceal cancer
Appendiceal cancer is a rare epithelial malignant tumor of the appendix, often discovered incidentally during exploration or appendectomy. Primary appendiceal cancers mainly include carcinoid tumors and adenocarcinomas. Metastatic appendiceal cancer is rare, mostly originating from ovarian cancer.
View detailsColon rupture
Colon rupture is caused by external trauma or internal factors, leading to a tear in the colon. The rupture or perforation can be a small hole, an incision, or a tear, which allows air and intestinal contents to enter the abdominal cavity, potentially leading to severe infection.

Cervical lymph node tuberculosis is a chronic infectious disease caused by Mycobacterium infection. It affects the cervical lymph nodes, leading to structural damage, inflammation, and necrosis of the lymphatic tissue. The typical symptom is enlarged cervical lymph nodes.
View detailsAcute cellulitis
Acute cellulitis is an acute, diffuse, purulent infection that occurs in the subcutaneous tissue, including the subfascial, intermuscular, or deep cellular tissue. The lesion is not easily localized, spreads rapidly, and has no clear boundary with normal tissue. The main symptoms are redness, swelling, heat, and pain in the affected area, followed by rapid spread of inflammation along the subcutaneous tissue to the surrounding areas, with significant swelling and severe pain. Deep acute cellulitis often presents with systemic toxic symptoms such as chills, high fever, headache, and fatigue.
View detailsAcute peritonitis
Acute peritonitis refers to an acute inflammatory response of the visceral and/or parietal peritoneum due to various irritations or injuries. It is a common surgical emergency, typically presenting with persistent abdominal pain, nausea, and vomiting.
View detailsAcute lymphadenitis
Acute lymphadenitis often results from other pyogenic infection foci, where pyogenic bacteria invade lymph nodes via lymphatic vessels, or local infection spreads to lymph nodes, leading to a suppurative infectious disease of the lymph nodes. The main symptoms include enlarged and painful lymph nodes. Acute cervical lymphadenitis is common in children. Acute mesenteric lymphadenitis is more prevalent in children under 7 years of age.
