Correct!
Incorrect
The answer is A: The anatomical location of the lump
Explanation
Why A is correct
See Close Inspection of the Lump. Option A is correct because the location of a neck lump is one of the most useful pieces of information in the whole examination, and you can gather it by looking before you touch. A midline lump is more likely to arise from the thyroid, a thyroglossal cyst (a cyst along the track the thyroid followed as it moved down from the tongue before birth) or a dermoid cyst (a cyst containing skin tissue). A lump in the anterior or posterior triangle, the areas in front of and behind the sternocleidomastoid muscle that runs from behind the ear to the collarbone, is more likely to be a lymph node, a salivary gland swelling or a branchial cyst (a cyst left over from the structures that form the neck in the embryo). Placing the lump on this map shortens your differential diagnosis before you palpate, and it tells you which dynamic tests, such as swallowing or tongue protrusion, are worth doing next. Size, skin changes, scars and facial movement still matter, but they refine the picture instead of locating it.
- Midline lump: More likely thyroid, thyroglossal cyst or dermoid cyst.
- Triangle lump: More likely a lymph node, salivary gland swelling or branchial cyst.
- Why location matters: It narrows the differential diagnosis before palpation.
Why the other options are incorrect
- B. The rough size and shape of the lump: Size and shape should be described, but they are much less specific for the tissue of origin. Many different structures can form a lump of the same size. Your answer
- C. Whether facial movement is symmetrical: Facial asymmetry is a targeted sign, because a malignant parotid lump can invade the facial nerve. It supports a parotid cause in particular; it is not the main observation used to place a lump anatomically. Your answer
- D. Any scars from previous procedures: Scars suggest previous biopsy or surgery, which is useful history. They do not tell you which structure the lump comes from. Your answer
- E. The appearance of the overlying skin: Skin changes such as redness, a punctum, tethering or ulceration suggest infection, a sebaceous cyst or malignancy. They describe the lump's behaviour but do not localise its source as directly as its position. Your answer
