Hydatid cyst is a parasitic disease that is endemic in Mediterranean areas, South America, North Africa, Australia, and Iran. Although the liver and lung are the most common involved organs, but the other organs in human body also can be involved by hydatid cyst. Chest wall involvement by hydatid cyst is a rare condition, which may be misdiagnosed as chest wall tumor in the endemic areas. Herei...

Autoimmune lymphoproliferative Syndrome (ALPS) is a rare inherited disorder of apoptosis. It usually presents with chronic lymphadenopathy, splenomegaly, and symptomatic cytopenia in a child. Herein, we report a 14-year-old boy with symptoms misdiagnosed as hemophagocytic lymphohistiocytosis who was treated before ALPS was diagnosed for the patient. This case should alert pediatricians to consi...

After curative treatment of Hodgkin’s lymphoma, increased risk of certain solid tumors has been reported. To best of our knowledge this is the first report of metachronous pancreatic adenocarcinoma which developed outside the previous radiation field in a patient with relapse Hodgkin’s lymphoma. Herein we present an 81-year-old female who developed pancreatic adenocarcinoma four yea...

Adrenal gland pseudocysts are not common conditions, and most of them are nonfunctional and asymptomatic. However, large pseudocysts may causes abdominal discomfort and have compressive effects on adjacent organs. They may rupture spontaneously or after trauma, and lead to retroperitoneal hemorrhage and surgical emergency. Herein, we report a case of 21-year-old female who presented with acute ...

Teratomas are tumors originated from mature or immature tissues. Teratomas are made up of one embryonic layer or all three embryonic layers (endoderm, mesoderm, or ectoderm). Herein we report a 41-year-old man who presented with vertigo, vomiting, and tinnitus. After physical examination, laboratory evaluation and performing computed tomography, cholesteatoma was diagnosed, however, during radi...

The vertical and rocking impedances of a rigid foundation resting on a semi-infinite transversely isotropic medium are obtained in the frequency domain. In the present approach, the contact pressure distribution on the soil foundation-interface is approximated by a linear combination of known pressure patterns. It is shown herein that the approximate solutions of spatial displacement distributi...

Focal epithelial hyperplasia or Heck’s disease is a benign, rare viral disease of the oral cavity and is associated with human papillomavirus 13 and 32 (HPV-13 and HPV-32). Most patients are children but adults may also be at risk. Clinically, the patients have multiple small white or pink papules on the mucosal surface of the lips, buccal mucosa and the tongue. In Iran, this disease seems to b...

Folliculosebaceous Cystic Hamartoma (FSCH) is a cutaneous hamartoma comprised of follicular, sebaceous and mesenchymal elements, and usually occurring during adulthood. Congenital and childhood presentations of this lesion are exceedingly rare. We describe herein a case of congenital FSCH on the midline and posterior region of the neck in a 1-year-old male infant and highlight the clinico...

Herein, we report the invention of a novel expeditious concept for oligosaccharide synthesis. Unlike the classic orthogonal strategy based on leaving groups, the reverse approach is based on orthogonal protecting groups, herein p-methoxybenzyl and 4-pentenoyl, which allows for efficient oligosaccharide assembly in the reverse direction.
