Symptoms of acne vulgaris include comedones (white heads), open comedones (black heads), papules (pimples), pustules (pus filled swellings), nodules (larger nodules) and cysts (fluid filled swellings).

These swellings usually develop on areas with a high concentration of sebaceous (oil) glands like the face, back, chest and shoulders. Patients who develop occupational acne can also develop lesions on other parts of their bodies like the hands.

Symptoms of acne scars include:

1. Ice Pick Scars which are deep holes with narrow openings on the skin. They have a V-shaped cross-section.

2. Boxcar Acne Scars which are round or oval or polygonal depressions with boxlike walls in the skin. They have a U-shaped cross-section.

3. Rolling Scars which are usually wide and shallow. They give the skin an uneven, wavy texture.

4. Hypertrophic Scars which are elevated above the skin and they are the same size as the original acne lesion.

5. Keloid Scars which are elevated above the skin and they extend outside the margins of the original acne lesion.

These cutaneous (skin) symptoms of amyloidosis can be divided into

1. Localized Cutaneous Amyloidosis Symptoms  which include:

a. Lichen amyloidosis is the most common type of primary localized cutaneous amyloidosis. It affects men more than women and especially those of Chinese descent. Patients presents with a very itchy, hyperkeratotic (scaly) papules (raised areas) which are reddish brown in color. These affected areas may coalesce to form large plaques on the pretibial regions (shins), thighs and feet.

b. Macular amyloidosis affects more women than men and especially those of Asian descent. Patients present with brownish grey spots which may join to form larger patches on their upper back and chest. These lesions may be associated with either severe  or mild pruritis (itch).

c. Nodular localized cutaneous amyloidosis (LCA) is the rarest type of primary localized cutaneous amyloidosis. Patients present with firm nodules which range in color from pink to brown. These lesions can be single or multiple and develop on the face, scalp, limbs, feet, soles, trunk and genitalia.

Nodular LCA lesions which are usually just a few centimeters in size or smaller are initially asymptomatic. This means that do not cause any symptoms and they can persist in this state for many years. Eventually patients present due to cosmetic reasons.

2. Systemic Cutaneous Amyloidosis Symptoms include:

a. Petechia (small purplish spots on the skin), purpura (purple colored spots and patches) and ecchymoses (larger reddish-purplish patches) are the most common cutaneous symptoms of primary systemic amyloidosis.

These develop on the skin and mucous membranes due to intracutaneous bleeding or the bleeding that occurs within the skin when the amyloid weakens the blood vessels. They commonly develop on the eyelids, axillae (armpits), umbilicus and around the groin and anal region.

b. Smooth, waxy, yellowish papules (small swellings), nodules (larger swellings) and plaques develop due to dermal infiltration by the amyloid. They commonly develop around the eyelids, in the mouth and on the limbs.

c. The nails may also become brittle, white and develop bands. There may also be onycholysis.

d. Patches of hair loss may also develop or the hair may thin uniformly.
