Uncommon metastatic journey: unusual breast metastases of medullary thyroid carcinoma: a case report.

Medullary thyroid carcinoma is a neuroendocrine tumor derived from thyroid C-cells. It is a rare aggressive tumor, known to metastasize to lymph nodes, liver, bones, and lungs. We report a case of a young patient with a family history of breast cancer, who developed breast metastases six months post-treatment for medullary thyroid carcinoma.

A rare case report of a myxoid liposarcoma arising from the broad ligament.

Myxoid liposarcoma (MLPS) is the second most prevalent subtype of liposarcoma. It is usually found in the deep tissues of the lower limbs and rarely in gynecologic tract. Herein we present the second case in the English literature of a primary MLPS arising from the broad ligament which was thought to be a borderline ovarian tumor.

Aggressive Behavior of Warty Squamous Cell Carcinoma of the Vagina Associated with Uterine Prolapsed: Unusual Report.

Warty squamous cell carcinoma (WSCC), is a rare variant of squamous cell carcinoma that occurs mostly in younger women, but can occur in old women. It is due to human papillomavirus (HPV) infection. This rare entity has been described in several organs such as vulva, cervix, and penis.

An Aggressive Presentation of Merkel Cell Carcinoma: A Case Report.

Merkel cell carcinoma (MCC) is a rare malignant neuroendocrine tumor more common in immunosuppressed old patients. It is characterized by a high frequency of local recurrence, regional nodal metastasis, distant metastasis, and low survival rate. The diagnosis of MCC is challenging due to its rarity and can be clinically mistaken for other skin cancer.

Clear cell gynecologic carcinomas: about 5 cases.

Clear cell carcinoma (CCC) can simulate yolk sac tumor if the location is ovarian. In this case, the morphological distinction between these tumors is often difficult, but immunohistochemistry, the determination of CA125, of alpha fetoprotein (AFP) and the response to chemotherapy are particularly useful for solving this differential diagnosis problem. Endometrial and vaginal localization is even rare and appears to be related to distilbene uptake for vaginal localization.

Prognostic factors and the role of pelvic lymphadenectomy in uterine leiomyosarcomas.

Objectives: Leiomyosarcomas are relatively rare uterine smooth muscle tumors. Surgery is the most common therapy choice for uterine leiomyosarcomas. However, controversy exists over the appropriate initial surgical management, especially about the role of lymph node sampling.

Investigation on the origin of sperm morphological defects: oxidative attacks, chromatin immaturity, and DNA fragmentation.

DNA fragmentation can be deleterious on spermatozoon morphology but the pathogenesis of teratozoospermia associated with DNA breaks is not fully understood, even if oxidative attacks and defects in chromatin maturation are hypothesized. Therefore, this study is one of the first to clarify on the underlying hypothesizes behind such observations. The objectives of our study were to assess the role of oxidative attacks in DNA damage pathogenesis in ejaculated spermatozoa from patients with isolated teratozoospermia.

Deletion of late cornified envelope genes, LCE3C_LCE3B-del, is not associated with psoriatic arthritis in Tunisian patients.

A deletion of two genes from the late cornified envelope (LCE), LCE3B and LCE3C within epidermal differentiation complex on chromosome 1 was shown to be associated with both psoriasis and psoriatic arthritis (PsA) in several populations. To assess whether this deletion may contribute to the genetic predisposition to PsA in Tunisia, a total of 73 patients with PsA and 120 healthy matched controls were screened for the deletion, LCE3C_LCE3B-del, and its tag SNP, rs4112788. We also evaluated a possible relationship between PSORS1 and LCE3C_LCE3B-del through genotyping two proxy markers to HLA-C (rs12191877 and rs2073048).

Failure to find evidence for deletion of LCE3C and LCE3B genes at PSORS4 contributing to psoriasis susceptibility in Tunisian families.

Background: Recently, it has been shown that a deletion in the late cornified envelope (LCE) gene cluster (LCE3C_LCE3B-del) is associated with susceptibility to psoriasis in European and Asian populations. However, no study of this deletion has been performed in the North African population. The aim of the present study was to investigate whether this deletion is associated with familial psoriasis in Tunisian population.

Linear IgA bullous dermatosis in tunisian children: 31 cases.

Background: Linear IgA bullous dermatosis (LAD) of children is relatively frequent in Africa.

Aim: We undertook this study to evaluate the frequency of this disease among autoimmune bullous diseases (AIBDs) in Tunisian children.

Materials And Methods: We present a 32-year retrospective study (January 1976 to December 2007).

Bullous dermatosis associated with gemcitabine therapy for non-small-cell lung carcinoma.

Gemcitabine considered is to be a well-tolerated cytostatic drug with little known side effects. Cutaneous reactions are well known but still rarely reported. We report the case of a 75-year-old man with stage IV non-small-cell lung carcinoma treated with combination of gemcitabine 1000 mg/m2 and cisplatin 75 mg/m2 repeated every 28 days, who developed bilateral cutaneous bullous lesions of lower limbs following gemcitabine administration.
