			Features:
			*[[Lamellar bone]] - has layering/lines (best seen with polarized light).
			*+/-Skeletal muscle (within the marrow space).

			Lesion, Distal Phalanx of Right Little Finger, Excision:
			- Dermal ossification without cartilage in benign skin with a thick keratin layer.
			- NEGATIVE for evidence of malignancy.

			===Block letters===
			<pre>
			LESION ("HETEROTOPIC OSSIFICATION"), RIGHT FEMUR, EXCISION:
			- BONE -- CONSISTENT WITH MUSCLE HETEROTOPIC OSSIFICATION.
			- NEGATIVE FOR MALIGNANCY.
			</pre>

			===Micro===
			The sections show laminar bone with a marrow space containing adipose tissue and benign skeletal muscle. The osteocytes show no nuclear atypia. No mitotic activity is appreciated.
