Pathology MCQ2

Pathology MCQ2:
A 23-year-old woman has noted a nodule on the skin of her upper chest. She reports that the nodule has been present for many years and has not changed in size. It is excised, and
the microscopic appearance is shown in the figure. Which of the following neoplasms is this lesion most likely to be?

A Fibroadenoma
B Hemangioma
C Leiomyoma
D Lipoma
E Melanoma
F Nevus





Explanation:
The small, discrete nature of this mass and its slow growth with nearly unchanged size suggest a benign neoplasm. The red color is consistent with vascularity. A hemangioma is a common benign lesion of the skin. Fibroadenomas arise in the breast. Leiomyomas, which are white, arise from
smooth muscle and are most common in the uterus. Lipomas are yellow fatty tumors that can occur beneath the epidermis. Melanomas are malignant and tend to increase in size
quickly; many are darkly pigmented. The benign counterpart to the melanoma is the nevus, which is quite common, but nevi are usually light to dark brown.So,  the correct option is B(Hemangioma).
