Secondary pulmonary syphilis: Case report and review of literature.

INTRODUCTION: Syphilis is a sexually transmitted disease that can affect numerous organs in its secondary or tertiary stages. We describe a case of secondary syphilis with pulmonary involvement and we present a literature review. PATIENTS AND METHODS: A 69-year-old male patient was admitted to hospital for dyspnoea and extended papular exanthema with palmoplantar involvement. The serological test for syphilis was positive. Ocular examination showed bilateral papillitis and retinal haemorrhage. Chest radiography revealed an interstitial alveolar infiltrate predominantly in the upper lobes, mild pleural effusion and hilar adenopathy. These infiltrates were slightly hypermetabolic on PET scan suggesting inflammatory or infectious origin. Treatment with intravenous penicillin G was effective on cutaneous, ocular and pulmonary manifestations. DISCUSSION: Lung involvement in secondary syphilis is poorly known and rarely described. We found 27 cases of pulmonary syphilis reported in English and the main European languages since 1967. Mean age at diagnosis was 46 years with clear male predominance (89%). HIV co-infection was declared in 5 cases. Treponema pallidum was found in 6 patients using PCR on bronchoalveolar lavage (BAL) (3 patients) or on a lung biopsy (1 patient), immunohistochemistry (IHC) on BAL (1 patient) and Giemsa staining on a pleural fluid sample (1 patient). Chest X-rays may show unilateral or bilateral infiltrates or nodules with or without pleural effusion or hilar adenopathy. Sub-pleural involvement is frequent and penicillin is the treatment of choice. CONCLUSION: Pulmonary syphilitic involvement should be suspected where pulmonary symptoms or radiological changes occur in secondary syphilis. IHC, special staining or PCR on BAL, pleural fluid or lung tissue are useful for the identification of spirochetes.

[Griscelli syndrome type 3: A new case]. / Syndrome de Griscelli de type 3 : un nouveau cas.

INTRODUCTION: Griscelli syndrome (GS) is a rare autosomal-recessive genetic disease characterized by hypopigmentation of skin and hair. We report a case of GS type 3 with late diagnosis. OBSERVATION: A 31-year-old female patient had presented depigmentation of the hair and eyebrows as well as diffuse skin hypopigmentation during childhood. Microscopic analysis of a hair shaft revealed irregularly distributed clumps of melanin. DNA sequencing showed a homozygous C103T (R35W) transition in exon 1 of MLPH, confirming Griscelli syndrome type 3. DISCUSSION: Three clinical phenotypes of GS have been described based on the underlying genetic defect. GS type 1 and 2 are associated respectively with a central nervous system dysfunction and an immune defect. GS type 3 is an isolated cutaneous form. Diagnosis is confirmed on microscopic examination of hair shafts. 15 cases of GS type 3 have been reported: 9 in males and 6 in females. Mean age at diagnosis is around 12 years. Nine of the reported patients were of Arab origin, four of Turkish origin, and one of Indian origin. R35W mutation was described in 9 cases and E98X and R35Q mutations were each found in one case. CONCLUSION: GS should be suspected in patients presenting gray silvery hair, particularly when these patients are of Arab or Turkish origin.
