Chapter 28 35-Year-Old Male with an Expanding Lump in the Thigh (Case 17)
PATIENT CARE
Clinical Thinking
• In your career, you will encounter many “lumps” and “bumps,” but few sarcomas; nonetheless, sarcoma should be kept in your “lump” and “bump” differential dx.
• Sebaceous cysts, lipomas, and hematomas will usually be recognized by inspection and palpation. The tests and imaging studies noted below are applicable when there is suspicion for sarcoma.
• Patients will frequently present with a small mass consistent with a lipoma, which has been present for a “long time.” Excision is warranted if the lesion is tender, expanding, or of concern to the patient, or for cosmetic reasons.
Tests for Consideration
Clinical Entities | Medical Knowledge |

Lipoma | |
PΦ | A lipoma is a benign soft tissue tumor of mature adipocytes. |
TP | Many patients have a hx of a lipoma that has been present for several years. The lesion is usually soft, mobile, subcutaneous, and nontender. When a patient states that a small mass has been present for a long time, excision is generally warranted if the lesion is tender, expanding, or of any concern to the patient. |
Dx | The dx of lipoma is made through hx and physical examination. Suspicious masses (e.g., firm, rapidly growing) require excision to exclude sarcoma. Incisional biopsy should be performed for larger masses greater than 3.0 cm in order to exclude the possibility of sarcoma prior to definitive surgery. |
Tx | Complete excision of a lipoma is usually curative. Care must be taken to excise the entire mass; a small piece left behind may regrow in the same area. |
