RESUMO
Anetoderma or macular atrophy is a rare skin condition of unclear pathogenesis, often associated with autoimmune diseases and skin damage from various infections. Human immunodeficiency virus (HIV), syphilis, and poxviruses have been implicated in the development of anetoderma. A 37-year-old male patient with HIV and recent unprotected sexual encounters presented with more than 400 skin lesions, consistent with Mpox. Symptomatic treatment for Mpox resulted in acute symptom resolution. However, 8 months later he developed papular anetoderma lesions in areas previously affected by Mpox. Biopsy confirmed the loss of elastic fibers in the affected skin areas, leading to the diagnosis of Mpox-induced anetoderma. This report presents a unique case of anetoderma following Mpox in an HIV-positive patient.

Monkeypox is a rare zoonotic disease with a progressive increase in cases among men who have sex with men (MSM) worldwide in recent months. New complications of this infection have been described. The aim of the study was to describe this new pattern of presentation of monkeypox at the level of the finger. We present the cases of three patients with monkeypox whitlow, a new clinical presentation of monkeypox. The patients were three MSM with ages ranging from 32 to 49â years. All three had involvement of the third finger of the dominant hand as well as skin lesions at other sites. Two of the three patients had severe inflammation in the digit and proximal arm and were treated with systemic corticosteroids with significant improvement. In two of the three cases we observed onychodystrophy as a complication. All patients reported sexual intercourse with previous digital-anal penetration with the affected finger, which may be the mode of transmission. Distinguishing features that need to be considered are discussed.

BACKGROUND: Syphilis is a sexually transmitted infection (STI) caused by the pathogen Treponema pallidum. Its incidence is increasing in our country, especially among men who have sex with men (MSM). Serological tests are still the most widely used technique for diagnosis. The need for an early diagnosis has prompted the introduction of fast techniques, such as Treponema pallidum detection by polymerase chain reaction (PCR) on mucocutaneous samples. The objective of this work is to analyse the sensitivity of this technique in a series of patients diagnosed with syphilis at our centre. METHODS: Retrospective review of all cases diagnosed with syphilis at our centre between May 2017 and May 2021. RESULTS: A total of 203 cases of syphilis were diagnosed with serologic tests: 33% were primary syphilis and 53.1% secondary syphilis. PCR for Treponema pallidum was performed in 117 (57,6%) cases. The sensitivity was highest (95,2%) when performed on samples from mucocutaneous ulcers in primary syphilis. This value decreased to 69,4% in secondary syphilis, although there were variations between the types of samples. CONCLUSIONS: The PCR test has a high diagnostic value when performed on ulcer exudates in patients with primary syphilis. Its most relevant advantages in clinical practice are the possibility of an early diagnosis before serological tests during the window period, the ability to confirm reinfections in patients with persistent positivity of reaginic antibodies and a history of treated syphilis. Nevertheless, given that a negative PCR test may not rule out infection by Treponema pallidum, serologic tests are still necessary for everyday practice.

Monkeypox is a previously rare viral zoonosis affecting predominantly the African continent. Since May 2022, an increasing number of cases with no known epidemiologic link to Africa have been reported for the first time in the rest of the world. We described the epidemiologic and clinical characteristics of all patients attended at our center until August 9 with a confirmed diagnosis of monkeypox. Forty-nine patients were included. The mean age was 37.6 years. Ninety-eight percent of patients were male, 96% were men who have sex with men, and 4% were heterosexual. Thirty-one percent of patients had a history of human immunodeficiency virus infection. Ninety-six percent of patients declared a unprotected sexual relationship before the onset of symptoms, and 41% had a history of recent travel. Ninety-eight percent of patients presented with cutaneous involvement affecting the genital (59%), perianal (41%), and perioral (35%) regions. Systemic symptoms were present in 80% of the patients and included lymphadenopathies (71%), asthenia (65%), fever (65%), headache (37%), arthromyalgias (45%), pharyngitis (35%), proctitis (29%), and dysuria (6%). Coinfection by other sexually transmitted infections was detected in 20% of patients. The sensitivity values of polymerase chain reaction test for monkeypox in urethral, anal, and oropharyngeal exudates analyzed were 88%, 79%, and 68%, respectively. Complications included a myopericarditis that represented the only hospitalized patient, edema (8%) and bacterial superinfection (4%). No deaths were reported. The findings of this case series support the sexual contact as the main route of transmission of the disease and highlight some atypical clinical presentations not described in endemic cases.

ABSTRACT: We describe 2 monkeypox cases in human immunodeficiency virus-positive men who have sex with men with undetectable viral loads. Both patients presented with the dory flop sign.

ABSTRACT: Herpes zoster is an acute, cutaneous viral infection caused by the reactivation of varicella-zoster virus. Genital dermatomes are involved in only up to 2% of cases and are probably underrecognized. We present a series of 7 genital herpes zoster cases diagnosed in our Unit of Sexually Transmitted Diseases. None of our patients were positive for HIV test, and only one was taking immunosuppressive medication. We recommend the use of molecular testings to confirm the diagnosis of varicella-zoster virus or herpes simplex virus infection in all cases of genital herpes-like lesions.
