Syphilis is a sexually transmitted disease caused by the spirochetes Treponema pallidum. Syphilitic spinal lesions present as erosive bone lesions often simulating spondylodiscitis or cancer. In this article we describe a rare case of cervical osteolytic lesion from tertiary syphilis. A 45-year-old male with axial neck pain, without fever presented with an isolated osteolytic lesion at C3. Tuberculous spondylitis was initially suspected. A new CT and contrast enhanced MRI of the cervical spine and of the neck showed an extention of the bone lesion at C3 with bilateral lymphadenomegaly. To confirm the diagnosis of tertiary syphilis, US-guided biopsy of the lymph nodes was performed. The patient was treated with i.m. benzylpenicillin 2.4 MIU and the follow-up showed clinical and radiological resolution of the condition. The aim of this case report is to raise awareness of tertiary syphilis in the differential diagnosis of lytic lesions of the spine among the spinal community.

Differential diagnosis of destructive osteolytic spinal lesions can be a diagnostic challenge. In this study, we described a rare case of spinal metastases from primary desmoplastic melanoma which had incorrectly been diagnosed and treated as tuberculous spondylodiscitis. An 82-year-old male patient with ongoing low back pain and a history of lumbar localized Pott’s performed a lumbar spine MRI that showed osteolytic lesion with first hypothesis of spondylodiscitis L2-L3. The patient was hospitalized and cause of worsening of the lumbar pain underwent a following series of non-diagnostic CT-guided and open lumbar biopsy at L2-L3 with unsuccessful antibiotic-antitubercular therapy. A new MRI revealed a worsening of previous lesions, extension of the osteolytic lesion at the level of L1-L2 and L3-L4 with neurological impairment. The diagnosis of metastatic melanoma was obtained with surgical decompression and open posterior biopsy procedure. The case described is pathognomonic of the difficulty in detecting the correct diagnosis in front of similar clinical and radiological manifestations. The presence of a previous Pott’s disease in the same involved vertebral site was of crucial importance in deflecting the correct diagnostic classification of the pathology, which was possible to ascertain only following an extensive biopsy sampling in the last surgery performed.
