  Acquired bilateral nevus of Ota-like macules
Acquired bilateral nevus of Ota-like macules were first described in 1984 as blue-brown or slate-gray, small patches that occurred on the lateral sites of the forehead, temples, upper eyelids, malar areas, root of the nose, and ala nasi, without ocular or mucosal pigmentation [1].
The macules are most often seen in women of Asian descent and usually appear in the fourth or fifth decade [2].
Acquired bilateral nevus of Ota-like macules are differentiated from bilateral nevus of Ota by the later age of onset and the lack of conjunctival, mucosal, and tympanic membrane involvement [1].

 NYU SoM - Dept. of Dermatology
Numerous tan-to-medium-brown macules and patches that measured 2 mm to 6 cm in diameter were present on the face, trunk, and extremities, with an increased density of smaller macules in the axillae and groin.
Although blue-red macules are characterized by their color and pseudoatrophic macules by their anetoderma-like appearance, there is considerable overlap between the two entities.
Blue-red macules have been observed in patients as young as five years of age, and pseudoatrophic macules may be present at birth.

The typical vitiligo macule is chalk white in color, has convex margins (as if the white areas were flowing into normally pigmented skin), is 5mm to 5cm or more in diameter, and is round, oval, or elongated in shape.
The focal type is characterized by one or more macules on a single site; in some cases, this may be an early evolutionary stage of one of the other forms of the disease.
The segmental type, which is uncommon, is characterized by one of several macules on one hand or one side of the body.

Three common red, flat lesions in the mouth are (1) the erythematous macule and erosion, (2) the purpuric macule, and (3) the granulomatous stage of the inflammatory hyperplasia.

 Final Diagnosis -- Case 190
The brown to fl, freckle-like hyperpigmented macules of PJS are commonly found on the buccal mucosa, nose, lips, and skin of the perioral and perianal regions.
Although the presence of mucocutaneous melanocytic macules is considered an important diagnostic criterion for PJS, a number of studies suggest that they are unreliable indicators, being present in only 80-90% of patients (Brigg, et al).
The absence of these macules in post-pubertal patients may mislead clinicians who rely upon a simple visual inspection of the skin to confirm a suspicion of PJS (Erbe).

The lance ovate hypopigmented macule (ash leaf macule) is the characteristic lesion of tuberous sclerosis.
The ash leaf macule may be seen in the general population; therefore it is considered only a tertiary criterion for tuberous sclerosis.
The ash leaf macules are not depigmented but hypopigmented, with functional melanocytes remaining in the affected areas that are normal in number but have smaller melanosomes and melanin content.

Background: Tinea versicolor is a common, benign, superficial cutaneous fungal infection usually characterized by hypopigmented or hyperpigmented macules and patches on the chest and the back.
In the case of hypopigmentation, tyrosinase inhibitors (resulting from the inhibitory action of tyrosinase of dicarboxylic acids formed through the oxidation of some unsaturated fatty acids of skin surface lipids) competitively inhibit a necessary enzyme of melanocyte pigment formation.
In hyperpigmented macules in tinea versicolor, the organism induces an enlargement of melanosomes made by melanocytes at the basal layer of the epidermis.
