[Characteristics of melanoma in Mexicans seen at "La Raza" National Medical Center].

Background: Melanoma is the third most common type of skin cancer in Mexico and represents 75% of skin cancer deaths. Dermoscopy is a diagnostic tool that increases early detection of melanoma compared to naked eye examination.

Objective: The aim of this study was to describe the clinical, dermoscopic and histological characteristics of patients with a confirmed diagnosis of cutaneous melanoma treated at the "La Raza" National Medical Center.

Dermoscopy in Selected Latin American Countries: A Preliminary Look into Current Trends and Future Opportunities Among Dermatology Residency Programs.

Introduction: Skin cancer remains a global public health burden. Dermoscopy is a useful technique that aids in early detection and increases diagnostic accuracy with adequate training. However, dermoscopy is not uniformly taught to residents worldwide.

Birth cohort-specific trends of sun-related behaviors among individuals from an international consortium of melanoma-prone families.

Background: Individuals from melanoma-prone families have similar or reduced sun-protective behaviors compared to the general population. Studies on trends in sun-related behaviors have been temporally and geographically limited.

Methods: Individuals from an international consortium of melanoma-prone families (GenoMEL) were retrospectively asked about sunscreen use, sun exposure (time spent outside), sunburns, and sunbed use at several timepoints over their lifetime.

Characterization of individuals at high risk of developing melanoma in Latin America: bases for genetic counseling in melanoma.

Purpose: CDKN2A is the main high-risk melanoma-susceptibility gene, but it has been poorly assessed in Latin America. We sought to analyze CDKN2A and MC1R in patients from Latin America with familial and sporadic multiple primary melanoma (SMP) and compare the data with those for patients from Spain to establish bases for melanoma genetic counseling in Latin America.

Methods: CDKN2A and MC1R were sequenced in 186 Latin American patients from Argentina, Brazil, Chile, Mexico, and Uruguay, and in 904 Spanish patients.

Near-visible light and UV photoprotection in the treatment of melasma: a double-blind randomized trial.

Background: Melasma is an acquired hyperpigmentation on sun-exposed areas. Multiple approaches are used to treat it, but all include broad ultraviolet (UV)-spectrum sunscreens. Visible light (VL) can induce pigmentary changes similar to those caused by UV radiation on darker-skinned patients.

Dermoscopy of non-pigmented eccrine poromas: study of Mexican cases.

Background: Eccrine poroma is a benign neoplasm that can mimick a malignant neoplasm dermoscopically. The characteristic vascular pattern of this tumor has not been established.

Objective: To evaluate dermoscopic features of non-pigmented eccrine poroma in Mexican patients.

Dermoscopic evaluation of nodular melanoma.

Importance: Nodular melanoma (NM) is a rapidly progressing potentially lethal skin tumor for which early diagnosis is critical.

Objective: To determine the dermoscopy features of NM.

Design: Eighty-three cases of NM, 134 of invasive non-NM, 115 of nodular benign melanocytic tumors, and 135 of nodular nonmelanocytic tumors were scored for dermoscopy features using modified and previously described methods.

Influence of time on dermoscopic diagnosis and management.

Background/objectives: Dermoscopy aids in clinical decision-making. However, time pressure is a common reason precluding its use. We evaluated the effect of time on lesion recognition and management decisions utilising clinical and dermoscopic images.

Accuracy in melanoma detection: a 10-year multicenter survey.

Background: Early excision is the only strategy to reduce melanoma mortality, but unnecessary excision of benign lesions increases morbidity and healthcare costs.

Objective: To assess accuracy in melanoma detection based on number-needed-to-excise (NNE) values over a 10-year period.

Methods: Information was retrieved on all histopathologically confirmed cutaneous melanomas or melanocytic nevi that were excised between 1998 and 2007 at participating clinics.

[The impact of dermoscopy in clinical practice].

For a long time, visual exploration has been the main strategy in dermatology. Melanoma diagnosis is established with symptoms like pruritus, scars and bleeding. The incidence of melanoma and its high mortality led to the use of dermoscopy, which has shown good results for identification, prevention and diagnosis of malign melanoma.

[Dermoscopy findings in malignant skin melanoma with metastases. A case report].

Melanoma is the result of the malignant transformation of normal melanocytes of the skin, which are responsible for the synthesis of melamine. It occupies the third place in frequency of skin cancer. Its incidence shows an annual increment of 3 to 7 % which varies in different populations.

[Correlation among simple observation and dermoscopy in the study of pigmented lesions of the skin].

Introduction: Dermoscopy began in 1663, and until 1971 was used to diagnose skin lesions.

Objective: To measure the correlation between simple observation and dermoscopy to diagnose pigmented skin lesions.

Methods: The study was conducted in Centro Médico Nacional La Raza.
