Topics for General and Systemic Pathology
Find educational topics for General and Systemic Pathology aligned with the Zambian tertiary curriculum.
Uterine and Endometrial Pathology
3 Questions
This topic covers a wide array of uterine conditions, from congenital anomalies to common tumors and cancers. Zambian tertiary students will study uterine malformations (e.g., septate, bicornuate uterus), endometritis, endometriosis, leiomyomas (fibroids), leiomyosarcoma, and endometrial carcinoma. A key learning objective is contrasting the benign, ubiquitous fibroid with its malignant counterpart, …
Primary Hyperparathyroidism
2 Questions
This topic details primary hyperparathyroidism, an autonomous overproduction of PTH, most commonly by a solitary parathyroid adenoma. Zambian university students will learn the classic clinical manifestations often summarized as "stones, bones, abdominal groans, and psychic moans." This includes nephrolithiasis (renal stones), bone disease (osteitis fibrosa cystica, osteoporosis), gastrointestinal disturbances (constipation, …
Secondary Hyperparathyroidism
No questions yet
This topic explores secondary hyperparathyroidism, a compensatory overactivity of the parathyroid glands driven by chronic depression of serum calcium levels. Zambian tertiary students will learn that the most common cause is chronic renal failure, where impaired phosphate excretion leads to hyperphosphatemia, which in turn lowers ionized calcium, stimulating PTH secretion. …
Amyloidosis and Congo Red Staining
6 Questions
This topic introduces amyloidosis as a systemic disorder of protein folding, where misfolded proteins deposit in tissues and impair function, with links to diseases like Alzheimer's and type 2 diabetes. The focus is on the diagnostic gold standard: Congo Red histology. Students in Zambian tertiary programs—such as diplomas and degrees …
Ovarian and Fallopian Tube Pathology
No questions yet
This topic addresses the complex pathology of the ovaries and fallopian tubes. Zambian tertiary students in pathology and gynecology will study non-neoplastic conditions like functional cysts and salpingitis (often part of PID), as well as the major categories of ovarian tumors. These include surface epithelial-stromal tumors (serous, mucinous), germ cell …
Hypoparathyroidism
No questions yet
This topic covers hypoparathyroidism, a condition of PTH deficiency leading to hypocalcemia. Zambian university students will study the major causes, including surgical removal or damage during thyroid surgery, congenital absence, autoimmune destruction, and familial forms. The clinical manifestations are primarily due to neuromuscular irritability from low ionized calcium, leading to …
Sirius Red and Miscellaneous Amyloid Stains
No questions yet
This topic explores alternative and supplementary histochemical methods for demonstrating amyloid, beyond the standard Congo Red. Sirius Red F3B is covered as a similar linear dye that also produces green birefringence under polarized light, often yielding more intense staining suitable for photography. Additionally, students are introduced to miscellaneous methods such …
Pathology of Pregnancy: Ectopic, Molar, and Complications
No questions yet
This topic covers critical pathological conditions of pregnancy, essential for Zambian students in obstetrics, midwifery, and pathology. You will study spontaneous abortion (miscarriage), ectopic pregnancy (focusing on tubal implantation), molar pregnancies (complete and partial hydatidiform mole), gestational trophoblastic neoplasia (including choriocarcinoma), and hypertensive disorders (preeclampsia/eclampsia). The focus is on etiology, …
Adrenal Cortex: Hypercorticism (Cushing Syndrome)
5 Questions
This topic provides an overview of Cushing syndrome, the clinical condition resulting from chronic glucocorticoid excess. Zambian tertiary students will learn the four main etiological categories: 1) Iatrogenic (exogenous glucocorticoids - most common), 2) Pituitary ACTH-secreting adenoma (Cushing's disease), 3) Adrenal cortical adenoma/carcinoma, and 4) Ectopic ACTH secretion (e.g., from …
