Background: Facial hypermelanosis is a significant cause of cosmetic disfigurement, social embarrassment and psychological morbidity affecting quality of life.

Objective: To study clinicoepidemlogic patterns of facial hypermelanoses among men.

Material And Methods: Medical records of all adult males presenting with facial hypermelanoses were analyzed for this retrospective cross sectional study for demographic details, duration, cosmetic usage, sun exposure, drug intake, infections, systemic or cutaneous diseases, and family history of hypermelanotic dermatosis.

Melasma, also known as chloasma or mask of pregnancy, presents clinically as hyperpigmented skin areas, which develop mostly in the face as a consequence of increased synthesis of melanin. The established treatment options, including topically applied agents and the use of various laser systems, mostly result in improvement but not in complete remission of the lesions. Because of its significant impact on quality of life and the limited effectivity of available treatment options, the management of melasma is challenging for the treating physician. Read More

Lasers are a very effective approach for treating many hyperpigmented lesions. They are the gold standard treatment for actinic lentigos and dermal hypermelanocytosis, such as Ota nevus. Becker nevus, hyperpigmented mosaicisms, and lentigines can also be successfully treated with lasers, but they could be less effective and relapses can be observed. Read More

History And Admission Findings: A 33-year-old female patient with chronic anorexia nervosa was admitted for inpatient psychosomatic treatment after a recent severe weight loss. In addition, an inflammatory bowel disease had been suspected in the past 4 years. The patient was convinced that the weight loss had purely organic reasons. Read More

Becker nevus syndrome is the association of Becker's nevus with breast hypoplasia and other ipsilateral bone or muscle changes. It is considered to be a hormone-dependent disorder caused by a disturbance in the activity of the androgen receptor that appears to be increased in Becker's nevus, which may influence the development of associated lesions. We present a relevant case of this syndrome due to the rare systematization of the lesions in addition to the exuberant extracutaneous involvement in this case. Read More

Background: Becker nevus is a nevoid melanosis, referred to as Becker nevus syndrome when it is associated with other anomalies. Our objectives were to report the occurrence of a Becker nevus with an underlying desmoid soft-tissue tumor; to review Mayo Clinic's experience with Becker nevi, concentrating on Becker nevi associated with bone, vascular, neural, and other soft-tissue abnormalities; to inform physicians of the Becker nevus syndrome; and finally to alert clinicians to evaluate a Becker nevus with its associations in mind.

Observations: A 46-year-old woman had a Becker nevus with an underlying desmoid-type fibromatosis (desmoid tumor) presenting clinically as a "painful dimple" within the nevus. Read More

Becker melanosis, also known as Becker nevus, is a relatively common cutaneous hamartoma. The condition is classically characterized by a unilateral, hyperpigmented patch with varying degrees of hypertrichosis on a peripubertal individual. As Becker nevi are generally singular in a given individual, there are very few reported cases of multiple or bilateral lesions. Read More

A 14-year-old boy had giant confluent brown patches that were bilaterally distributed on his back, chest, and upper arms, and partially covered by dark coarse hairs. A clinical diagnosis of Becker nevus was made and confirmed histopathologically. We report this patient for the rarity of presentation. Read More

The Q-switched ruby laser (694 nm, 25-40 nsec) is an effective and safe therapeutic device for the treatment of tattoos and well-defined, benign, pigmented epidermal and dermal lesions. Because of its selective mode of action, dermal pigments of natural and artificial origin are destroyed photothermically and removed without scar. This method is exceptionally suited for the elimination of lay and professional tattoos, traumatic tattoos, and permanent makeup. Read More

We report a 4-year-old Caucasian girl with congenital skin lesions consisting of hyperpigmented macules that were bilateral and roughly symmetrical, covered with terminal hair and located on the scapular regions, shoulders, and arms. A cutaneous biopsy specimen showed the histologic pattern of Becker nevus. We discuss the classification of this case in the context of the published literature. Read More

The Q-switched ruby laser (QSRL) with its wavelength of 694 nm and a pulse duration of around 40 nsec is an effective modality for the removal of tattoos and cutaneous pigmented lesions. Based on the principle of selective photothermolysis, selective damage to cutaneous pigment or pigmented cells is possible, allowing the scar-free elimination of endogenous or exogenous pigment in the skin. Main indications for the treatment with the QSRL are tattoos (amateur, professional, accidental, or cosmetic) and lentigines but the QSRL can also be used for lightening or even removing other pigmented lesions such as nevus spilus or café au lait macules.

Melanosis naeviformis of Becker (MNB) can be associated with hypoplasia of soft tissue or extremities, spina bifida and scoliosis of the vertebral column. We have investigated 50 patients (42 men, 8 women) with MNB radiologically. Scoliosis was diagnosed in 13 patients (26%). Read More

Becker melanosis is a dermatosis characterized by hyperpigmentation and hypertrichosis in absence of cells nevus; its frequency is unknown an its presentation is rare in the infancy; appearance usually during puberty. In the last years its association to anomalies of development increase the importance of this entity. We present the case of 4 years old girl considered the youngest report in the literature, with affection of trunk and right leg associated to minimum shorten of right leg. Read More

Theoretically, Becker's melanosis or hairy epidermal nevus and smooth muscle hamartoma are two quite separate entities. In fact, there are cases which could be considered as intermediate. As a matter of fact, a slight underlying smooth muscle hyperplasia can be seen in Becker's nevus; on the other hand, hypermelanosis of the basal layer and hypertrichosis may be encountered in smooth muscle hamartoma.

A case is reported of aggressive cellular blue nevus of the scalp. Intracranial pigmentation in association with a melanocytic nevus of the scalp may indicate either benign coexisting melanosis, local extension, or invasive malignancy. The importance of accurate diagnosis is discussed, and the need to be prepared to carry the excision deep enough to include the dura is illustrated. Read More

Histological investigations were performed in 11 subjects suffering from melanosis naeviformis Becker. Apart from the well-known epidermal alterations such as basal hyperpigmentation, slight acanthosis and growth of coarse hair, dermal changes were found in each case. The dermis was considerably thickened and contained numerous small and/or large bundles of smooth muscle without relation to cutaneous adnexa. Read More

Lentigo maligna is the preinvasive stage of lentigo maligna melanom, which is a specific type of cutaneous malignant melanom found almost exclusively in the head and neck area. The distinguishing features and the biological behavior of this disease are discussed. Emphasis is placed on early diagnosis by clinical differentiation from other pigmented lesions and by biopsy specimen. Read More

A healthy 14-year-old Norwegian male developed a typical Becker's naevus on the left shoulder and upper scapular region, about six months after an intracutaneous BCG-vaccination in the homolateral junction of the shoulder and upper arm. The evolution of the lesion had been modified by exposure to sunlight during the following six years, with partial fading of the hyperpigmentation. Biopsies taken from the centre and from the edge of the lesion at the age of 19 years showed the usual histological picture seen in cases of Becker's naevus, but focal areas within the periphery showed a chronic granulomatous infiltrate of lupoid pattern in the dermis, mainly follicular and perifollicular in distribution.

Benign melanocytic lesions include lentigo, ephelid (freckle), pigmented nevus, sacral spot, blue nevus, and combined nevus and blue nevus. Malignant melanocytic lesions are melanomas, which arise from melanocytes at the epidermodermal junction, or, rarely, from blue nevi. They usually originate in brown plaques known as lentigo maligna, in pigmented nevi, or in normal skin. Read More
