Kikuchi-Fugimoto's Disease (KFD), also known as histiocytic necrotizing lymphadenitis, is most frequently seen in young women and has been associated with autoimmune disorders such as polymyositis and systemic lupus erythematosus. It is generally a self-limiting disease with recovery time ranging from weeks to months. A typical presentation of KFD includes painful cervical lymphadenopathy, usually consisting of unilateral involvement of the posterior cervical chain. To date, this condition has not been described in patients with sickle cell disease. We present 2 cases of KFD, 1 in a patient with sickle beta(o)-thalassemia (Sbeta(o)thal) and 1 in a patient with sickle cell anemia with hereditary persistence of fetal hemoglobin (HbS-HPFH). Both patients were young-adult African American females who presented with fever and unilateral tender cervical lymphadenopathy. Extensive infectious disease testing, including cultures and viral serologies, were all negative. Imaging was negative for abscesses. The first patient had a preceding history of benign carcinoid tumor and idiopathic thrombocytopenic purpura. The second patient had no history of autoimmune syndromes but was on hydroxyurea therapy at the time of her presentation; the first had never taken hydroxyurea. Treatment strategies included prednisone therapy in the first case and watchful monitoring in the second. Recovery time was approximately 2 months for each patient. Both developed thyroid disease subsequent to their episode of KFD. Currently, both patients are asymptomatic with no recurrence of KFD or active autoimmune disease.

The diagnosis of acute autoimmune rheumatic disorders in sickle cell disease (SCD) can be challenging. Polymyositis is an inflammatory myopathy which, like SCD, may present with myalgia but is usually associated with proximal muscle weakness. We describe an adolescent boy presenting with limb pain, difficulty in mobilisation, with progressive loss of motor function and later bulbar weakness. Investigations showed massive elevation of creatine kinase, and MRI and muscle biopsy findings consistent with severe polymyositis. The patient was treated with corticosteroids, intravenous immunoglobulin and intensive rehabilitation therapy. He made a good recovery and was discharged on azathioprine and prednisolone. In the context of SCD, multisystem symptoms, unexplained muscle pain and weakness, unresponsive to conventional treatment in the presence of steady state haemoglobin, should alert the clinician to autoimmune phenomena. Key factors in making a diagnosis are an autoimmune screen and early discussion with a rheumatology expert.

Identification of certain abnormalities of the chest wall can be extremely helpful in correctly diagnosing a number of syndromic conditions and systemic diseases. Additionally, chest wall abnormalities may sometimes constitute diagnoses by themselves. In the present pictorial essay, we review a number of such conditions and provide illustrative cases that were retrospectively identified from our clinical imaging database. These include pentalogy of Cantrell, Klippel-Feil syndrome, cleidocranial dysplasia, Poland syndrome, osteopetrosis, neurofibromatosis type 1, Marfan syndrome, Gardner syndrome, systemic sclerosis, relapsing polychondritis, polymyositis/dermatomyositis, ankylosing spondylitis, hyperparathyroidism, rickets, sickle cell anemia, thalassemia, tuberculosis, septic arthritis of the sternoclavicular joint, elastofibroma dorsi, and sternal dehiscence.
