Internalised capillaries, neuromyopathy and myalgia.

Internalised capillaries, neuromyopathy and myalgia.

Internalised capillaries are described in the muscle fibres of two adult males who complained of exertional myalgia. In one patient, "bundles" of internalised capillaries were found in 2% of the Type 1 fibres and many of the Type 1 fibres exhibited non-specific cytoarchitectural changes. The other had hereditary motor and sensory neuropathy (HMSN) Type 2 and his muscle biopsy exhibited the more...

Colchicine neuromyopathy: a report of six cases.

In this report we describe 6 patients who developed neuromyopathy after the administration of colchicine. All patients presented with proximal muscle weakness, elevated serum creatine kinase (CK) levels, and neurop...
