For each description of a lump(s) below, give the most likely cause for the clinical
findings. Each option may be used only once.
1 A 22-year-old man presents with a lump on the scalp. Examination reveals a
smooth, spherical, tense lump. A small punctum can be seen on the surface.
2 A 33-year-old man presents with a swelling on the upper arm that has been
growing slowly for a number of years. Examination reveals a soft, compressible,
non-tender, lobulated mass.
3 A 28-year-old man presents with a painless swelling on the dorsum of the right
hand. Examination reveals a smooth, spherical, tense, 1.5 cm swelling. The overlying
skin can be drawn over it.
4 A 29-year-old man presents with two mobile fusiform-shaped lumps on the
forearm. Each swelling feels like firm rubber and causes tingling in the hand on
pressure.
5 A 65-year-old woman presents with a rapidly growing lump just below the eye.
Examination reveals a 2 cm smooth, round, skin-coloured lump with a black
central core. The lump is freely mobile over subcutaneous tissues.
