The following list of clinical terms are approximate synonyms, alternative descriptions, or common phrases that might be used by patients, healthcare providers, or medical coders to describe the same condition. These synonyms and related diagnosis terms are often used when searching for an ICD-10 code, especially when the exact medical terminology is unclear. Whether you're looking for lay terms, similar diagnosis names, or common language alternatives, this list can help guide you to the correct ICD-10 classification.

an autoimmune disorder mainly affecting young adults and characterized by destruction of myelin in the central nervous system. pathologic findings include multiple sharply demarcated areas of demyelination throughout the white matter of the central nervous system. clinical manifestations include visual loss, extra-ocular movement disorders, paresthesias, loss of sensation, weakness, dysarthria, spasticity, ataxia, and bladder dysfunction. the usual pattern is one of recurrent attacks followed by partial recovery (see multiple sclerosis, relapsing-remitting), but acute fulminating and chronic progressive forms (see multiple sclerosis, chronic progressive) also occur. (adams et al., principles of neurology, 6th ed, p903)

a form of multiple sclerosis characterized by a progressive deterioration in neurologic function which is in contrast to the more typical relapsing remitting form. if the clinical course is free of distinct remissions, it is referred to as primary progressive multiple sclerosis. when the progressive decline is punctuated by acute exacerbations, it is referred to as progressive relapsing multiple sclerosis. the term secondary progressive multiple sclerosis is used when relapsing remitting multiple sclerosis evolves into the chronic progressive form. (from ann neurol 1994;36 suppl:s73-s79; adams et al., principles of neurology, 6th ed, pp903-914)

the most common clinical variant of multiple sclerosis, characterized by recurrent acute exacerbations of neurologic dysfunction followed by partial or complete recovery. common clinical manifestations include loss of visual (see optic neuritis), motor, sensory, or bladder function. acute episodes of demyelination may occur at any site in the central nervous system, and commonly involve the optic nerves, spinal cord, brain stem, and cerebellum. (adams et al., principles of neurology, 6th ed, pp903-914)

human abca12 wild-type allele is located in the vicinity of 2q35 and is approximately 207 kb in length. this allele, which encodes glucosylceramide transporter abca12 protein, plays a role in both the membrane localization of glucosylceramide and other lipids in lamellar granules and in cholesterol transport. mutation of the gene is associated with autosomal recessive congenital ichthyosis (arci) types 4a and 4b (harlequin).

a very rare, autosomal recessive inherited skin disorder present at birth. it is characterized by the presence of a transparent membrane encasing the newborn. this membrane sheds in about two weeks after birth to reveal generalized scaling and skin erythema.
