Overview
Physical exam findings of merkel cell cancer include red/violaceous skin mass that appear in sun exposed areas.
Physical examination
Physical examination of patients with merkel cell cancer is usually remarkable for flesh-colored or bluish-red, intracutaneous nodules.
Appearance of the Patient
- Patients with merkel cell cancer usually appear normal.
Vital Signs
- Mostly all vitals are within normal limits.
Skin
- Skin examination of patients with merkel cell cancer is significant for:[1][2][3]
- A mass that appear in sun exposed areas of the skin
- Mass that usually 1-2 cm
- Non-tender, firm, shiny, flesh-colored or bluish-red or pink colour intracutaneous nodule
- Presence of a polymorphous vascular pattern is very characteristic to merkel cell cancer
- Dome-shaped or raised nodule
- Red/violaceous skin mass
- +/- Crusting and ulceration
- According to National Cancer Database the following are the most common locations of merkel cell cancer in decreasing order:
- Head and neck
- Upper limbs(UL) and shoulder
- Lower limbs(LL) and hip
- Trunk
HEENT
- HEENT examination of patients with merkel cell cancer is usually shows the following:[4][5]
- Mass measuring 2 X 3 cm most commonly in the right nasal ala.
- Due to the mass effect patients with merkel cell cancer might experience nasal obstruction.
Lungs
- Pulmonary examination of patients with merkel cell cancer is usually normal.
Heart
- Cardiovascular examination of patients with merkel cell cancer is usually normal.
Abdomen
- Abdominal examination of patients with merkel cell cancer is usually normal.
Back
- Back examination of patients with merkel cell cancer is usually normal.
Genitourinary
- Genitourinary examination of patients with merkel cell cancer is usually normal.
Neuromuscular
- Neuromuscular examination of patients with merkel cell cancer shows the following:[6][7]
- Clonus may be present
- Sudden onset of severe headache
- Gait disturbance
- Confusion
- Brain metastasis from merkel cell carcinoma
