What is a cyst or tumor ranging in size from a pea to an orange?

A steatoma, commonly referred to as a sebaceous cyst, is a type of cyst that can vary significantly in size, sometimes reaching dimensions from that of a pea to that of an orange. Steatomas are typically filled with sebaceous material and result from the blockage of sebaceous glands. They are usually benign and can occur anywhere on the body where sebaceous glands are present. This characteristic of size variation and common occurrence makes steatomas distinctive, as they are the type of cyst most typically associated with these size ranges.

The other options, while related to skin and tissue growths, do not specifically describe cysts that exhibit the same size variability and characteristics. Cystadenomas, for example, are benign tumors that arise from glandular tissue, while neoplasms represent any type of abnormal growth, either benign or malignant. Fibromas are benign tumors that develop from connective tissue but do not typically present the same cystic characteristics or size range as a steatoma. Thus, understanding these distinctions helps clarify that steatoma is the best fit for the described characteristics.
