Inflammatory Phase Wound Healing MCQ – Predominant Cells at 48 Hours

📘 Theme: Plastic Surgery – Wound Healing (NEET SS / INI-CET High Yield)

Clinical Wound Healing MCQ

A 28-year-old male presents 48 hours after a clean surgical incision. The wound shows mild erythema without pus. Which of the following cells is predominantly responsible for the inflammatory phase at this stage?

A. Monocytes
B. Lymphocytes
C. Fibroblasts
D. Platelets

Answer: A. Monocytes (macrophages)

Explanation

During the inflammatory phase of wound healing (24–72 hours), monocytes migrate into the wound and differentiate into macrophages. These cells are the key regulators of healing, performing phagocytosis and releasing growth factors that initiate the proliferative phase.

Why other options are incorrect

  • Lymphocytes: Seen in later or chronic inflammatory phases, not dominant early.
  • Fibroblasts: Key cells of proliferative phase responsible for collagen deposition.
  • Platelets: Important in immediate hemostasis phase (first few hours only).

High-yield teaching points

  • 0–24 hrs: Neutrophils dominate.
  • 24–72 hrs: Macrophages (from monocytes) dominate ⭐
  • Macrophages are the “director cells” of wound healing.
  • They regulate angiogenesis, fibroblast activation, and collagen synthesis.

Cystic tumors Pancreas Imaging MCQ

A 52-year-old woman undergoes imaging for vague abdominal discomfort. CT scan shows a well-circumscribed lesion in the head of the pancreas with multiple small cysts and a central stellate scar. Serum CEA and CA 19-9 levels are normal. What is the most likely diagnosis?

A. Mucinous cystic neoplasm
B. Intraductal papillary mucinous neoplasm (IPMN)
C. Serous cystadenoma
D. Solid pseudopapillary tumor

Answer: C. Serous cystadenoma

Explanation

Serous cystadenoma (microcystic adenoma) is a benign pancreatic cystic tumor characterized by a microcystic appearance and a central stellate scar (sunburst pattern). Tumor markers such as CEA and CA 19-9 are typically normal, helping differentiate it from mucinous lesions.

Why other options are incorrect

  • Mucinous cystic neoplasm: Macrocystic, occurs in body/tail, elevated CEA, malignant potential.
  • IPMN: Communicates with pancreatic duct, causes ductal dilation, may raise CA 19-9.
  • Solid pseudopapillary tumor: Seen in young women, mixed solid-cystic, no central scar.

High-yield teaching points

  • Central stellate scar + microcystic lesion = serous cystadenoma.
  • Normal CEA favors serous over mucinous lesions.
  • Surgery indicated only if symptomatic, large, or uncertain diagnosis.

Pelvic floor

📘 Theme: Mock Test – 1 March 2026

Pelvic Floor Mechanics

During anorectal manometry, a patient demonstrates preservation of resting continence despite severe internal anal sphincter damage. Which structure is most responsible for maintaining continence in this scenario?

A. Pubococcygeus
B. Iliococcygeus
C. Puborectalis
D. External anal sphincter

Answer: C. Puborectalis

Explanation:
The puborectalis muscle forms a U-shaped sling around the anorectal junction and is the most critical muscle for maintaining fecal continence. Its tonic contraction maintains an acute anorectal angle, preventing involuntary stool passage. Even with internal anal sphincter damage, the puborectalis sling can preserve continence.

Teaching Points:

  • Puborectalis forms a sling at the anorectal junction.
  • Maintains anorectal angle (~80–90°) → continence.
  • Relaxes during defecation → angle straightens.
  • Dysfunction → dyssynergic defecation or fecal incontinence.
  • Key compensatory mechanism when sphincters are weak.
