Pleomorphic carcinoma of the lung revealed by uncommon colonic metastasis: An exceptional case report with literature review.

Lung pleomorphic carcinoma is a rare and aggressive cancer that uncommonly metastasizes to the colon and only a few case reports have been published thus far. We present an exceptional case of colon metastasis from lung pleomorphic carcinoma in a 68-year-old man which was revealed by large bowel perforation, and we review the previous three published cases. Metastasis to the bowel from primary lung malignancy often lacks specific symptoms which result in delayed diagnosis.

The Prognostic Significance of CD10 Expression in Invasive Breast Carcinoma in Tunisian Patients.

Background: Breast cancer is the first female cancer worldwide. Its prognosis depends mainly on pathological stage and histological grade. These classical prognostic factors are essential but may be insufficient to predict the outcome of the disease.

Multiple asymptomatic papules following breast cancer treatment.

Acquired lymphangiectasia (AL) represents superficial lymphatic dilatation caused by different processes. It is a consequence of lymphatic damage by an external cause; leading to obstruction of local lymphatic drainage.1 We report a case of AL of the breast in a 45-year-old woman mimicking warts.

Immunohistochemical Overexpression of Cyclin D1 in Tunisian Invasive Breast Carcinoma Women.

Background: Breast cancer represents the most frequent cancer and cause of death in women worldwide and in Tunisia. Cyclin D1 is a gene of cell cycle regulation. It represents a potential oncogene in invasive breast cancer; however; the results are conflicting.

Primary cutaneous Rosai-Dorfman-Destombes disease with features mimicking IgG4-related disease: A challenging case report and literature review.

Rosai-Dorfman-Destombes disease (RDD) is a rare histiocytic disorder affecting lymph nodes as well as extranodal sites. Although cutaneous involvement in RDD is common, primary cutaneous RDD is a distinct and not well-documented entity with unknown aetiology and non-specific clinicopathological features. We report a case of a 57-year-old patient, who presented with an indolent skin nodule in the left sub-nipple area.

Antioxidant role of selenium against maneb-induced cardiotoxicity in mice.

The current study was conducted to assess the beneficial effect of selenium (Se) on maneb-induced cardiotoxicity and fatty acid alterations in adult mice. Swiss albino male mice were assigned into four experimental groups. The first group consisted of negative controls.

A case of a verrucous and pseudotumoral mass on the leg that resolved with cryotherapy.

Various clinical forms of cutaneous leishmaniasis can be encountered such as: ulcerated, lupoïd, sporotrichoïd and other rare forms (eczematiform, erysipeloid, psoriasiform, verrucous, and pseudotumoral). We report an atypical presentation of verrucous and pseudotumoral cutaneous leishmaniasis that resolved following a course of cryotherapy.

Compound blue nevus: A misleading pigmented melanocytic tumor.

Compound blue nevus had clinical and histological similarities with other heavily pigmented melanocytic tumor, like the pigmented epithelioid melanocytoma. Distinctive genomic aberrations have allowed differentiating it. The defining characteristic of blue nevi family is the presence of activating mutations in the G protein α-subunits, GNAQ and GNA11.

A diagnostic pitfall of a sternal mass.

Primary sternal lymphoma represents a rare entity which must be evoked in front of a sternal mass especially as its treatment is different from that of sarcomas, the principal etiology of sternal masses.

Zinc alleviates maneb-induced kidney injury in adult mice through modulation of oxidative stress, genotoxicity, and histopathological changes.

Zinc is one of the important essential trace minerals to human health due to its antioxidant properties. The present study was conducted to elucidate its potential protective role against maneb-induced nephrotoxicity. For this purpose, animals were randomly divided into four groups of six each.

[Tubulo-papillary apocrine adenoma in association with syringocystadenoma papilliferum].

Tubulo-papillary apocrine adenoma (TAA) is a very rare sweat gland tumor. TAA in association with syringocystadenoma papilliferum (SCP) is exceptional. A 2-year-old Tunisian child developed a mixed tumor on the scalp: TAA in association with SCP.

A spindle cell myoepithelioma of parotid gland : a case report.

Background: Myoepthelioma is a rare salivary gland tumor which is usually located in parotid gland and in minor salivary glands.

Case Report: We report a case of myoepithelioma arising in an accessory paritid gland in a 47-yearold woman who presented with a slowly expanding subcutaneous nodule on the left cheek, that was within the parotid gland at surgical resection . This tumor was composed of spindle cells.

[Eosinophilic cellulitis: About a new pediatric case].

Wells' syndrome or "eosinophilic cellulitis" is characterized by clinical features of cellulitis and histological pictures of eosinophils infiltrate of the dermis with some « flame » figures. This is a very rare disease in the pediatric age. We report the case of a 14-month-old boy, presented with two farms painful nodular brownish lesions in the thigh and back of the foot as well as multiple erythematous papular and vesicular lesions on the forehead, cheeks, limbs and trunk.

Primary manifestation of small Lymphocytic Lymphoma in the Prostate: A case report.

We report a case of Lymphocytic Lymphoma presenting with primary manifestation in the prostate. A 82 year-old man presented to emergency department with acute urinary retention. Digital rectal examination revealed a voluminous and firm prostate.

Mammary fibroadenoma with pleomorphic stromal cells.

Unlabelled: The presence of enlarged and pleomorphic nuclei is usually regarded as a feature of malignancy, but it may on occasion be seen in benign lesions such as mammary fibroadenomas. We present such a case of fibroadenoma occurring in a 37-year-old woman presenting with a self-palpable right breast mass. Histological examination of the tumor revealed the presence of multi and mononucleated giant cells with pleomorphic nuclei.

Hepatoid adenocarcinoma of the gallbladder.

Hepatoid adenocarcinoma is a rare variant of extrahepatic adenocarcinoma which behaves like hepatocellular carcinoma in morphology and functionality. We present a rare case of hepatoid adenocarcinoma of the gallbladder which invades deeply the liver bed, in a 59-year-old woman. Histologically, most of the mass in the gallbladder was composed of cells with eosinophilic cytoplasm arranged in a trabecular pattern, which resembled hepatocellular carcinoma.
