  • Epidemic of venereal treponematosis in wild monkeys: a paradigm for syphilis origin. [Journal Article]
    New Microbes New Infect. 2020 May; 35:100670.Mediannikov O, Fenollar F, … Raoult D
  • Treponema pallidum infections have been primarily known as slightly contagious mucocutaneous infections called yaws (tropical Africa and America) and bejel (subtropical North Africa). T. pallidum emerged as a highly infectious venereal syphilis agent in South America, probably about 500 years ago, and because of its venereal transmission, it quickly caused a worldwide pandemic. The disease manife…
  • Syphilitic Chancre of the Lip. [Journal Article]
    Am J Dermatopathol. 2020 Apr 21 [Online ahead of print]Calvo DF, Cassarino D, Fernandez-Flores A
  • Syphilis is a sexually transmitted disease caused by Treponema pallidum. The primary stage of the disease (the chancre) mainly involves the genital areas. Extragenital areas are involved in 5%-14% of cases, many of which occur in the oral cavity. Among the extragenital locations, the lip is the most frequent; however, despite this, published cases of the chancre of the lip are few. We present a c…
  • Primary Syphilis Presenting As a Chronic Lip Ulcer. [Case Reports]
    Cureus. 2020 Feb 24; 12(2):e7086.Porterfield C, Brodell D, … Scott G
  • Syphilis is usually a sexually transmitted infection caused by the spirochete Treponema pallidum. Primary syphilis classically presents as a painless, ulcerated lesion on the genitals. However, the primary lesion is not restricted to this site and appears wherever the spirochete enters through the skin. The symptomatology and appearance of the primary lesion can also vary.  We present a case of a…
  • Multi-syphilitic gummas in pituitary and cerebellopontine angle in a patient. [Journal Article]
    Pituitary. 2020 Jun; 23(3):253-257.Xia K, Guo Z, … Zhong C
  • CONCLUSIONS: Syphilitic gummas in pituitary and CPA are similar to benign or malignant brain tumors, easily leading to misdiagnosis. Gumma should be considered in differential diagnosis when a patient has unexplained nervous system symptoms or signs and imaging findings suggest intracranial mass in syphilis seropositive patients.
  • A Case of Secondary Syphilis with the Extragenital Chancre on the Nipple. [Case Reports]
    Case Rep Dermatol Med. 2020; 2020:2391907.Wang XY, Juliandri , … Xu Y
  • Syphilis is a sexually transmitted disease caused by Treponema pallidum. The signs and symptoms of syphilis vary depending on which of the four stages it presents. The primary stage of syphilis classically presents with a painless ulcer (chancre). We report a case of the extragenital chancre on the nipple which is examined from skin biopsy and immunohistochemistry. This case showed that it is imp…
  • An exophytic and symptomatic lesion of the labial mucosa diagnosed as labial seborrheic keratosis. [Case Reports]
    Int J Clin Exp Pathol. 2019; 12(7):2749-2752.Feng H, Liu B, … Chen Q
  • Seborrheic keratosis is a common benign epidermal tumor that occurs mainly in the skin of the face and neck, trunk. The tumors are not, however, seen on the oral mucous membrane. Herein, we describe a case of labial seborrheic keratosis confirmed by histopathology. A healthy 63-year-old man was referred to our hospital for evaluation and treatment of a 2-month history of a labial mass with mild p…
  • Rollet's mixed chancre in Brazilian pregnant women: An unusual case report. [Case Reports]
    Int J Infect Dis. 2020 Feb; 91:57-59.de Oliveira D, Rosa LD, … Dos Reis HLB
  • Syphilis is a sexually transmitted infection (STI) caused by the bacterium Treponema pallidum and has shown a significant increase in recent decades. It may be associated with other STIs such as soft chancre or chancroid, which is an uncommon infection in Brazil. The presence of ulcerated genital lesions is associated with a higher risk of HIV transmission. An accurate clinical and laboratory dia…
  • [Lentigines]. [Journal Article]
    Pan Afr Med J. 2019; 33:190.Agharbi FZ
  • Chancroid (also known as soft chancre and ulcus molle) is a sexually transmitted disease (STD) due to the Ducrey's bacillus (or Haemophilus ducreyi) characterized by chancre at the site of ulcerated inoculation associated with lymphadenopathy. The disease manifests as a small pinkish papule at the site of penetration of the bacterium. After an incubation period ranging from 24 hours to 15 days (o…
  • [Chancroid]. [Journal Article]
    Pan Afr Med J. 2019; 33:185.Agharbi FZ
  • Chancroid (also known as soft chancre and ulcus molle) is a sexually transmitted disease (STD) due to the Ducrey's bacillus (or Haemophilus ducreyi) characterized by chancre at the site of ulcerated inoculation associated with lymphadenopathy. The disease manifests as a small pinkish papule at the site of penetration of the bacterium. After an incubation period ranging from 24 hours to 15 days (o…
  • Neurosyphilis. [Case Reports]
    Semin Neurol. 2019 08; 39(4):448-455.Gonzalez H, Koralnik IJ, Marra CM
  • Neurosyphilis is caused by the bacterium Treponema pallidum subspecies pallidum (T. pallidum). The organism gains entry into the central nervous system (CNS) early (primary syphilis or chancre phase) in the course of infection. While most patients are able to mount an immune response that effectively clears CNS invasion without long-term complications, a minority go on to develop asymptomatic or …
  • Early syphilis: risk factors and clinical manifestations focusing on HIV-positive patients. [Journal Article]
    BMC Infect Dis. 2019 Aug 16; 19(1):727.Arando M, Fernandez-Naval C, … Vall-Mayans M
  • CONCLUSIONS: Control of syphilis remains a challenge. Similar to prior studies, HIV-positive patients were found to engage more often in sexual behaviors associated with syphilis than HIV-negative patients. Clinical manifestations were rather similar in both groups, although anal chancre was most common in HIV-positive patients. Various strain types of syphilis were found, but no clinical associations were identified.
  • Lymphatic spread in an immunocompetent adult. [Case Reports]
    Med Sante Trop. 2019 May 01; 29(2):139-141.Ghariani Fetoui N, Aounallah A, … Nouira R
  • Cutaneous tuberculosis with lymphatic spread is rarely described. We report the case of a woman aged 38, immunocompetent, working in a fruit sorting center, who consulted us for ulceration of the left third finger that had persisted for four months, following a prick from a prickly pear. Physical examination revealed a nodular, erythematous, and ulcerative lesion of the left third finger, associa…
  • [A chancre instead of cancer]. [Case Reports]
    Ned Tijdschr Geneeskd. 2019 07 18; 163Prins FM, Lock MTWT, … van der Meer GT
  • CONCLUSIONS: This case demonstrates that a full medical history and thorough physical examination can prevent the need for costly and invasive diagnostics.
  • Cutaneous tuberculosis: A great imitator. [Review]
    Clin Dermatol. 2019 May - Jun; 37(3):192-199.Chen Q, Chen W, Hao F
  • Tuberculosis (TB) is still prevalent in many developing countries and can pose a new potential threat to global health due to international migration. As an uncommon form of extrapulmonary TB, cutaneous TB is complicated in its clinical manifestation, pathogenesis, and classification. Cutaneous TB can be divided into two major categories, true cutaneous TB and tuberculid, depending on the source …
  • Dermatologically challenging syphilis presentation. [Case Reports]
    Int J STD AIDS. 2019 06; 30(7):707-709.Katz AR, Johnson DW, … Kobayashi K
  • An atypical early primary syphilis case presentation with multiple umbilicated papular lesions on the penis and a nonreactive syphilis serology was misdiagnosed as molluscum contagiosum. Over a period of eight weeks, prior to dermatologic consultation, the papules enlarged, ulcerated, and healed. New plaque and patch formation on the penis and scrotum led to a differential diagnosis of inverse ps…
  • Forty cases of acquired oral syphilis and a review of the literature. [Review]
    Int J Oral Maxillofac Surg. 2019 May; 48(5):635-643.Schuch LF, da Silva KD, … Tarquinio SBC
  • The aim of this study was to describe 40 cases of acquired oral syphilis (AOS) and to discuss the distribution of demographic characteristics, clinical features, and differential diagnosis of the disease. A retrospective study was conducted covering a 17-year period at a single institution in southern Brazil. Moreover, a literature review was performed through a search of the PubMed database for …
