Understanding Paraneoplastic Pemphigus
Paraneoplastic pemphigus is a medical condition that was first identified in 1990. This autoimmune disorder occurs when the body’s immune system mistakenly attacks the skin and mucous membranes due to antigens associated with an underlying neoplasm, or tumor. The symptoms of this condition can range from the formation of crusts over raw lesions to severe and widespread eruptions on the mucous membranes. It is important to note that both individuals with malignant and benign tumors are equally susceptible to developing paraneoplastic pemphigus.
In terms of treatment, standard protocols involve wound healing techniques and the use of corticosteroids. However, it is disheartening to know that the mortality rate associated with this condition is alarmingly high, reaching close to 90 percent.
Paraneoplastic Cerebellar Degeneration
Paraneoplastic cerebellar degeneration is a rare condition that is observed in approximately one to three percent of all cancer cases. It is commonly associated with breast and gynecological cancers and is characterized by the extensive loss of Purkinje neurons. These neurons are responsible for the release of the neurotransmitter GABA. Individuals with this condition experience symptoms such as worsening vertigo and lack of coordination, which often appear months before the cancer diagnosis. The diagnosis of paraneoplastic cerebellar degeneration necessitates a specialized PET/CT scan. Fortunately, with proper understanding, some cases can be effectively managed through immunotherapy.
