Cystic mass of the right iliac fossa: don't forget about lymphatic malformation.

BJR Case Rep 2021 May 22;7(3):20200165. Epub 2020 Dec 22.

Department of Radiology, University Hospital Center IBN SINA, Mohammed V-Souissi University, Rabat, Morocco.

Lymphatic malformation or cystic lymphangioma is a benign tumour of the lymphatic vessels. It is more commonly reported among children and has polymorphic clinical presentations. The diagnosis is based on imaging but requires histological confirmation. The treatment of choice is surgical excision for the abdominal and symptomatic localization. We report the case of a 30-year-old female who consulted for right iliac fossa pain mimicking an acute appendicitis. The physical examination revealed a slight tenderness in the right iliac fossa without fever or palpable mass. Though the biological screening was normal, the imaging exploration has revealed the presence of a multiloculated cyst located in the right iliac fossa at the ascending colon and measuring 15 cm. The mass matches with lymphatic malformation. Therefore, a laparoscopy was performed, and complete resection of the cystic tumor was accomplished with right hemicolectomy. The histologic exam has confirmed the diagnosis. Colonic lymphatic malformation is a rare and benign tumour, requiring a complete surgical excision to minimise any recidivism. The definitive diagnosis remains histological.

Kaposi sarcoma of the adrenal gland: A report of two cases with a review of the literature.

J Cancer Res Ther 2021 Apr-Jun;17(2):606-608

Department of Pathology, Ibn Sina Teaching Hospital, Rabat, Morocco.

Kaposi sarcoma (KS) is a low-grade vascular neoplasm commonly involving mucocutaneous sites, while adrenal gland involvement is exceptional. The anaplastic variant is a rare entity characterized by marked cellular pleomorphism, increased mitosis, worse prognosis, and an increased metastatic potential. The diagnosis remains on histology and immunohistochemistry. We describe two cases of primary adrenal KS to report on this exceptional presentation of KS: the first case is a 67-year-old female with anaplastic KS wit fatal outcome. The second case is a 56-year-old male who presented a classic KS of the adrenal gland. Until now, no standard efficient treatment regimens have been clearly identified. There is a need for a further understanding of anaplastic KS's biology, and collecting a sizable patient cohort remains essential to review treatment outcome.

Primary Hodgkin lymphoma of the ulnar nerve: the first case report with review of the literature.

J Surg Case Rep 2021 May 20;2021(5):rjab185. Epub 2021 May 20.

Department of Pathology, Ibn Sina Teaching Hospital, Abderrahim Bouabid Avenue, Rabat 12000, Morocco.

Hodgkin lymphoma is a lymphoid malignancy characterized by minority population of neoplastic cells (Reed-Sternberg cells and its variants) within a reactive inflammatory background. It encompasses two entities: classical HL (∼95% of cases) and nodular lymphocyte predominant HL (∼5% of cases). Primary lymphoma of peripheral nerves (PLPN) represent a very rare condition, since only 19 cases have been reported in the English literature to date, all of which are of a non-HL phenotype. A 20-year-old female presented an intramural mass of the ulnar nerve. Histological analysis revealed a Classical Hodgkin lymphoma. Further investigations failed to reveal nodal or extranodal involvement. PLPN is a very rare entity. There is a need for further understanding of this unusual lymphoma presentation.

An unusual cause of multiple embolic strokes: cardiac myxoma, about a case.

J Surg Case Rep 2021 Mar 22;2021(3):rjab063. Epub 2021 Mar 22.

Cardiovascular Surgery A Department of Ibn Sina University Hospital Center, Mohammed V University of Rabat, Rabat City, Morocco.

Cardiac myxomas are the most common primary intracardiac tumors, accounting for 50% of all cardiac neoplasms, with an estimated frequency of 0.5/million/inhabitants/year. Presenting symptoms are related to cerebral or peripheral embolism, and/or intracardiac obstruction. Thus, urgent management of myxoma is mandatory due to embolism's risk. Herein, we report the case of an 82-year-old woman with a myxoma of the left atrium, revealed by a multiple ischemic strokes, to raise awareness of this entity.

Retroperitoneal leiomyoma of gynecologic type: a case report and review of the litterature.

J Surg Case Rep 2020 Dec 24;2020(12):rjaa489. Epub 2020 Dec 24.

Department of Pathology, Ibn Sina Teaching Hospital, Rabat, Morocco.

Retroperitoneal leiomyomas are rare benign tumors with smooth muscle differentiation, with only ~1001 cases reported in the English literature to date. Because of its scarcity and non-specific presentation, the preoperative diagnosis might be challenging. On histology, these neoplasms share the same macroscopic, morphological and phenotypic features with uterine leiomyoma; thus, they are referred to as leiomyoma of gynecologic type. Herein, we describe a case of a voluminous retroperitoneal leiomyoma in a 51-year-old woman with a history of total hysterectomy to raise awareness about this condition, as its differential diagnosis might be challenging.

Adrenocortical sarcomatoid carcinoma: a case report and review of the literature.

J Surg Case Rep 2020 Jul 16;2020(7):rjaa211. Epub 2020 Jul 16.

Department of Pathology, Ibn Sina Teaching Hospital, Rabat, Morocco.

Adrenal sarcomatoid carcinoma (ASC) is a very rare aggressive variant of adrenocortical carcinoma showing carcinomatous and sarcomatous differentiation. It is a poorly differentiated carcinoma with poor prognosis. The diagnosis requires careful histological and immunohistochemical investigation. We describe a new case of ASC to raise awareness on this extremely rare entity. A 27-year-old woman presented with a right flank pain. Imaging revealed a tissular mass of the right adrenal gland without metastases. After adrenalectomy, histology revealed sheets of epithelioid cells that stained for synaptophysin and Melan-A; and spindled cells staining for S-100. We have reported the clinical and histopathological features of ACS's case; as it is an extremely rare cancer with a challenging diagnosis. There is a need for a further understanding of ASC's biology to improve it poor prognosis.

Calcifying Fibrous Tumor of the Mesentery: A Case Report and a Review of the Literature.

Clin Pathol 2020 Jan-Dec;13:2632010X20930689. Epub 2020 Jun 23.

Department of Pathology, Ibn Sina Teaching Hospital, Rabat, Morocco.

Background: Calcifying fibrous tumor (CFT) is a rare entity, with a distinctive histological presentation, initially reported as childhood fibrous tumor with psammoma bodies. It is a benign hypocellular fibrous neoplasm calcifications and lymphoplasmacytic infiltrate. The CFTs may involve many sites, including gastrointestinal tract, pleura, abdominal cavity, and neck. The diagnosis might be challenging due to histological overlaps with other mesenchymal tumors. The prognosis is good. We describe herein the case of a 53-year-old woman with an incidentally diagnosed CFT of the mesentery.

Case Presentation: A 53-year-old woman presented to the surgery department with a 2-year history of an anterior abdominal hernia. A computed tomographic scan of the abdomen failed to demonstrate any evidence of a mesenteric nodule. The patient underwent surgical treatment. Careful exploration during the excision of herniated sac revealed a solitary nodule of the mesentery. Local excision was performed. On gross, it was a well-demarcated nodule. Microscopically, the tumor consisted of an abundant paucicellular hyalinized collagen with calcifications; associated to a sparse mononuclear inflammatory infiltrate.

Conclusions: Calcifying fibrous tumor is a benign lesion. The diagnosis is based on histology, because clinical and radiological features are nonspecific. Awareness of this entity is crucial to distinguish it from other mesenchymal tumors especially in the gastrointestinal tract.
