[Subcutaneous nodules with malignant presentation, but caused by infection].

Three patients, a woman aged 32, a boy aged 6.5 and a man aged 56 years, presented with a subcutaneous mass suggesting a malignancy: respectively a rubbery swelling, painful to the touch below the left scapula, a partly massive, partly soft swelling on the inside of the left upper leg, and a non-fluctuating mass near the right eighth rib, parasternally. Additional diagnostic investigation revealed an infectious cause: respectively Mycobacterium tuberculosis, Bartonella henselae and Salmonella typhi. Antimicrobial therapy was successful. Subcutaneous masses suspected of being a benign or malignant tumour are sometimes caused by an infection. The differential diagnosis is extensive. Sometimes the travel anamnesis yields helpful information. It is concluded that besides histopathological examination, microbiological investigation can play a major role in the evaluation of subcutaneous masses.

Cervical lymphadenopathy in the dental patient: a review of clinical approach.

Lymph node enlargement may be an incidental finding on examination, or may be associated with a patient complaint. It is likely that over half of all patients examined each day may have enlarged lymph nodes in the head and neck region. There are no written guidelines specifying when further evaluation of lymphadenopathy is necessary. With such a high frequency of occurrence, oral health care providers need to be able to determine when lymphadenopathy should be investigated further. Although most cervical lymphadenopathy is the result of a benign infectious etiology, clinicians should search for a precipitating cause and examine other nodal locations to exclude generalized lymphadenopathy. Lymph nodes larger than 1 cm in diameter are generally considered abnormal. Malignancy should be considered when palpable lymph nodes are identified in the supraclavicular region, or when nodes are rock hard, rubbery, or fixed in consistency. Patients with unexplained localized cervical lymphadenopathy presenting with a benign clinical picture should be observed for a 2- to 4-week period. Generalized lymphadenopathy should prompt further clinical investigation. This article reviews common causes of lymphadenopathy, and presents a methodical clinical approach to a patient with cervical lymphadenopathy.

[Cat scratch pneumonia: a case report].

Pasteurella multocida infections can be caused by scratches or bites of many animals including pets. An unrecognized infection can lead to severe complications such as arthritis, osteomyelitis, respiratory infections and even meningitis or endocarditis. We present the case of a woman affected by soft tissue infection caused by Pasteurella multocida complicated by bacteremia and pneumonia.
