Lupus vulgaris manifestation
as a destructive nose and facial tumor.

Lupus vulgaris is the
most frequent manifestation of cutaneous tuberculosis, but in Europe it is
limited to isolated cases. Mainly immunocompetent individuals are affected
by this result of an endogenous reinfection on a lymphogenous-less
frequently hematogenous-pathway. Lupus vulgaris has been observed to develop
in more than 50% of all patients who already suffer from other
manifestations of tuberculosis. The development of a squamous cell carcinoma
in the lupus vulgaris is a rare complication; therefore, lupus vulgaris is
deemed a facultative precancerosis.A 68-year-old female Serbo-Croatian
patient presented with an extensive ulcerative nose and facial tumor. Her
anamnesis included a squamous cell carcinoma of the nose that had been
excised alio loco 3 years before. Further examinations revealed enlarged
cervical lymphoma on both sides, and pulmonary metastases were also
suspected. The tumor biopsy revealed a necrotic, granulomatous inflammation.
No acid-fast rods were seen on Ziehl-Neelsen stain. The tuberculous origin
of this ulcerative skin tumor-the lupus vulgaris-as an endogenous
reinfection of pulmonary tuberculosis manifestation was confirmed by the
detection of Mycobacterium tuberculosis DNA in polymerase chain reaction and
the growth of Mycobacterium tuberculosis colonies in the bacterial culture
(skin biopsy and bronchial secretion). The skin tumor as well as the
pulmonary manifestation were successfully treated with combined
tuberculostatic therapy and showed a dramatic response within 3 months.

Lupus vulgaris is a
progressive form of cutaneous tuberculosis occurring in a person with a
moderate to high degree of immunity. It is the most common type of cutaneous
tuberculosis. Lupus vulgaris can be mimicked by several other skin
conditions, and a 69-y-old female is described with an extremely long
history of extensive infiltrative skin lesions with abundant scaling. The
lesions were localized on the right arm and forearm, and on the right
lateral surface of the chest. The diascopic test was positive. Moreover, a
large atrophic scar was seen in the region of right cubital fossa resulting
in contracture of the right elbow joint. The histopathology strongly
suggested the diagnosis of tuberculosis. The final diagnosis of tuberculosis
was confirmed by PCR examination. A polychemotherapeutic regimen (ethambutol
1250 mg/d, rifampicin 600 mg/d and isoniazid 300 mg/d) was successfully
employed for the treatment of skin lesions. |
