An extreme unilateral muscular atrophy of the shoulder and upper arm region was a symptom of juvenile
ankylosing spondylitis
in a 20-year-old female patient. No pathological patterns were found in electromyographic, bioptic, and tomographic (CT, NMR) investigations. The muscular atrophy was caused by a shoulder arthritis with severe erosive damage. The false assumption of a neurological disorder and the disregard of anamnesis and low back pain delayed for several years an accurate diagnosis. After the onset of an arthritis of hip joints a
collagen disease
with myositis was supposed falsely in spite of normal electromyographic results. The unusual muscular atrophy around the shoulder joint probably must be interpreted as a consequence of reflex inhibition and partly due to inactivity. A real myositis seems to not be probable, because newer investigations in contrast to earlier findings show no evidence for inflammatory muscle disease in
ankylosing spondylitis
.

Livedoid vasculopathy has been accepted as a nonvasculitic disorder, but authentic vasculitis in the underlying subcutis can occur in cases of
collagen disease
and polyarteritis nodosa. We report a case of livedoid vasculopathy with underlying subcutaneous necrotizing venulitis in a 42-year-old carrier of hepatitis B virus. The patient also had a 15-year history of
ankylosing spondylitis
that was currently in remission. Skin lesions revealed superficial ulceration, purpura, atrophie blanche, and reticulate erythema on the lower extremities, and a skin biopsy showed a minimal dermal perivascular lymphocytic infiltrate with marked fibrin thrombi and fibrin deposits along luminal vessel walls, consistent with features of livedoid vasculopathy. However, necrotizing venulitis characterized by a predominant lymphocytic infiltrate in and around the vessel wall with marked fibrinoid vessel wall necrosis was found in the underlying subcutaneous tissue. A direct immunofluorescence study detected immunoglobulin M and C3 deposits in the papillary dermis. The patient responded well to oral aspirin and a prostaglandin analogue and was well controlled with a compression bandage. Vasculitic lesions in the underlying subcutis may have been overlooked in cases in which livedoid vasculopathy has been considered as a nonvasculitic disorder because our case demonstrates that livedoid vasculopathy can be accompanied by subcutaneous vasculitis.
