ABSTRACT
The isolated thoracic parietal localization is a very rare shape of tuberculosis. It often leads to a diagnosis problem with the parietal tumours requiring surgical biopsy. We report a case of tubercular abscess localized in the antero-superior part of the thoracic wall with a second abdominal localization without any pulmonary localization. It was a 56-year-old woman presenting a swelling in the right side of the sternum accompanied after some months by a second swelling of the right flank of the abdomen, for one year. The radiological and biological explorations were in favour of a double localization parietal tumour. The diagnosis of certainty has been made by the histological exam of the surgical biopsy and the bacteriological exam of the trans-parietal withdrawal of the collection. The classic tuberculosis treatment has been maintained during 9 months with a good clinico-radiological evolution. Through this observation, we try to study the anatomo-clinical particularities and to clear the diagnostic difficulties of this affection
ABSTRACT
Melanomas of digit is rare, accounting for 1% of all cutaneous melanomas. We report a new case. Our purpose is to discuss the clinicopathological characteristics and the difficulties encountred in establishing diagnosis of this rare tumor. We report the case of a 25 years old woman, who consulted for nodular and ulcerated lesion of the right index, located in the external face of the metacrapo-phalangial joint. The nodule was biopsied and histopathologic exam concluded to spitzoid melanoma. The surgical margins were involved. The patient refused surgical recovery. She consulted 3 years later with axillary lymph nodes. A wide excision of the tumor with lymph node biopsy were made. Histological study concluded to a tumoral residu incompletely excided with lymph node metastases. Amputation of the second digit with dissection of the axillary lymph nodes was made. The surgical margins were tumor free. Lung metastases appeared with a follow up of two months. The patient died early after starting chemotherapy with Deticen. In our report, clinical presentation was misleading causing a diagnosis and therapeutic delay. Pathologically, all the histological types of melanoma were described in the digit except spitzoid melanoma

Cutaneous dirofilariasis is a zoonosis which mainly occurs in dogs and cats. Human dirofilariasis is rare. At our knowledge, only five cases of human dirofilariasis were reported in Tunisia. We report here two new cases of cutaneous dirofilariasis arising in two 19 and 21 year-old patients. The first one was admitted for surgical excision of a paraombilical cutaneous nodule. The second patient presented with multiple erythematous and pruriginous papules. In both cases, the histological examination revealed the presence of a worm diagnosed as Dirofilaria repens. The evolution was favourable after surgical resection in the first case and spontaneously in the second case
