We report a rare case of metastatic non-small-cell lung cancer in a 43-year-old woman with a history of smoking. The tumor secreted human chorionic gonadotropin and its beta subunit (BetaHCG). The patient presented with amenorrhea, a positive pregnancy test and chest pain. A physical examination and investigations revealed no pregnancy, and it was determined that a paraneoplastic syndrome stemm...

The association between nephrotic syndrome (NS), hemophagocytic lymphohistiocytosis (HLH), and certain paraneoplastic syndromes has been documented in the literature. However, nephrotic changes as part of paraneoplastic syndromes are rare in lymphoid malignancies, particularly in non-Hodgkin lymphoma. We report the sudden onset of acute renal failure and NS in a 14-year-old male who initially p...

Colorectal cancer usually presents with alterations in the bowel habit. Less commonly, the presenting symptoms may be part of a paraneoplastic syndrome. Metastasis can occur by lymphatic or hematogenous spread, most frequently to the lungs and liver. We present the case of a 56-year-old man admitted with paraneoplastic polymyositis due to a poorly differentiated colon adenocarcinoma. The evolut...

Autoimmune encephalitides are a group of syndromes that may present with subacute onset of disorientation, personality changes, memory loss and most prominently seizures. Earlier reports of this entity were from patients with paraneoplastic limbic encephalitis, however autoimmune etiologies have also been described in patients with non-paraneoplastic encephalitis [1]. The Alpha 3 ganglionic ace...

Paraneoplastic neurological anti-Hu syndrome is one of the most frequent remote effects of cancer and usually manifests as encephalomyelitis combined with peripheral neuropathy. Subacute sensory neuronopathy, which results from the inflammatory destruction of sensory neurone cell bodies in the dorsal root ganglia, is thought to be the principal presentation of peripheral neuropathy. In addition...

Malignant acanthosis nigricans is a rare paraneoplastic skin syndrome mostly associated with gastric adenocarcinoma. Florid cutaneous papillomatosis and tripe palms syndrome are considered to be abortive clinical variants of acanthosis nigricans. Clinical manifestations include pruritic, hyperkeratotic and hyperpigmented plaques with a subsequent formation of velvety papillomas in the involved ...

Paraneoplastic neurological syndromes (PNS) are remote effects of cancer on the nervous system. An overview of the management of classical PNS, i.e. paraneoplastic limbic encephalitis, subacute sensory neuronopathy, paraneoplastic cerebellar degeneration, paraneoplastic opsoclonus-myoclonus, Lambert-Eaton myasthenic syndrome and paraneoplastic peripheral nerve hyperexcitability is given. Myasth...
