A 47 year old woman complains of postcoital bleeding, nearly as heavy as menses. The most likely origin of her bleeding would be cervical :
First, I need to recall the common causes of postcoital bleeding. Postcoital bleeding often points to cervical pathology. The most common causes include cervical cancer, cervical polyps, and cervicitis. Since the bleeding is heavy, cervical cancer comes to mind, especially in a woman of perimenopausal age. Cervical cancer, particularly squamous cell carcinoma, is known to present with contact bleeding.
Now, looking at the options, the correct answer would be cervical cancer. But wait, what about cervical polyps? They can also cause bleeding, but usually the bleeding is less heavy and more intermittent. Cervicitis might cause bleeding too, but it's often associated with discharge and infection. Endometrial causes are less likely here because the bleeding is postcoital and heavy, which is more typical of cervical issues.
Let me think again. The age of the patient is 47, which is perimenopausal. Cervical cancer is more common in older women, and the heavy postcoital bleeding is a red flag. So the most likely origin is cervical cancer. The other options like polyps or infections might not present with such heavy bleeding.
Wait, could it be endometrial? The question specifies the origin is cervical, so the options are cervical. So, cervical cancer is the answer. The other options like cervical polyps or erosion might not cause such heavy bleeding. Also, cervical intraepithelial neoplasia (CIN) can lead to bleeding but is usually not as heavy.
So, the correct answer should be cervical cancer. The explanation would be that postcoital bleeding, especially heavy, is a classic presentation of cervical cancer. The other options are less likely due to the nature of the bleeding.
**Core Concept**
Postcoital bleeding is a classic clinical presentation of cervical pathology, with cervical cancer being the most common cause in perimenopausal women. This is due to the friable nature of malignant tissue, which bleeds easily upon contact during intercourse.
**Why the Correct Answer is Right**
Cervical cancer, particularly squamous cell carcinoma, presents with **postcoital bleeding** due to vascular proliferation and ulceration in the lesion. The heavy bleeding described here aligns with malignant tissue's inability to form stable clots. Cervical cancer is also more prevalent in women over 40, matching this patient’s age. Diagnostic confirmation requires colposcopy and biopsy.
**Why Each Wrong Option is Incorrect**
**Option A:** Cervical polyps typically cause **light spotting**, not heavy bleeding.
**Option B:** Cervical erosion (ectropion) may lead to **irritation bleeding**, but it is usually minimal and not as heavy as menses.
**Option C:** Cervicitis (inflammation) can cause bleeding, but it is often associated with **malodorous discharge** and is unlikely to produce such severe hemorrhage.
**Clinical Pearl / High-Yield Fact**
Never ignore **postcoital bleeding** in women over 40—it is a **red flag for cervical cancer**. Remember the mnemonics: **"
