In fibroid which is not seen:
**Core Concept**
Fibroids, also known as uterine leiomyomas, are benign tumors arising from the smooth muscle layer of the uterus. They are a common cause of abnormal uterine bleeding, pelvic pain, and infertility in women. Fibroids can be classified based on their location (intrauterine, submucosal, intramural) and size.
**Why the Correct Answer is Right**
The correct answer is related to the histological characteristics of fibroids. Fibroids are typically composed of uniform, well-differentiated smooth muscle cells with an absence of atypical cells. However, the presence of **pleomorphism** (variation in cell size and shape) and **necrosis** is not characteristic of fibroids. These features are more commonly seen in malignant tumors, such as leiomyosarcomas.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is a common feature of fibroids, which can be classified based on their location and size.
**Option B:** Fibroids can indeed cause **anemia** due to chronic bleeding, leading to symptoms such as pallor and weakness.
**Option C:** **Hemorrhage** can occur in fibroids, especially if they are submucosal or intramural, leading to heavy menstrual bleeding.
**Clinical Pearl / High-Yield Fact**
Fibroids are a common cause of **abnormal uterine bleeding** in women of reproductive age, and their symptoms can be managed with medication, surgery, or minimally invasive procedures.
**Correct Answer:** D.
