Pseudo-Fibrokeratoma: An Unusual Presentation of Subungual Squamous Cell Carcinoma in a Young Girl

An interesting case of subungueal squamous cell carcinoma in a 13-year-old girl is presented. The tumor presented as a pseudo-fibrokeratoma with melanonychia on the index finger. Biopsy was diagnostic and treatment consisted of Mohs micrographic surgery and secondary intention wound healing. This is one of the youngest patients ever reported with subungueal squamous cell carcinoma, and there is only one more case of pseudo-fibrokeratoma and melanonychia reported as initial skin lesions.     

Cervico-occipital teratoma in the newborn infant. Case report

A case of cervico-occipital teratoma in a neonate is presented. This is the third reported case of teratoma in this unusual location and the first excised during the neonatal period. The radiographic and histological examination, treatment, and follow-up findings in this case are presented, along with a review of the literature.     

Spontaneous rupture of the spleen: Two case reports

Two cases of spontaneous rupture of the spleen are reported: one in a case of infectious mononucleosis with splenomegaly, the other in a spleen with multiple hemangiomas. King, in 1941, presented the only other case of splenic rupture in mononucleosis reported in the literature. Both of the cases presented herein recovered following splenectomy.     

Solitary metastasis of renal cell carcinoma to urethra

A case report of a solitary metastasis to the urethra from previously resected renal cell carcinoma is reported. The patient presented with total gross painless hematuria. We believe this is the first such case to be reported.     

An unusual cause of postoperative detrusor overactivity

Fallopian tube prolapse through a ruptured vagina is a rare, but well-documented, gynaecological condition. The majority of cases reported in the literature complicated vaginal hysterectomy and presented with vaginal bleeding and pelvic pain. We report a case after abdominal hysterectomy, which presented with urinary symptoms, an unreported presentation, and was managed successfully via the vaginal route. An update on the cases reported in the literature is also presented.     

Atresia of the foramen of Monro resulting in severe unilateral hydrocephalus with subfalcial herniation and infratentorial diverticulum

A case of severe unilateral hydrocephalus associated with ventricular diverticulum and subfalcial herniation secondary to likely atresia of the foramen of Monro is presented. Both atresia of the foramen of Monro and ventricular diverticulum are rare conditions in hydrocephalus. The case presented here is the third reported case with both unique entities.     

High Grade Infective Spondylolisthesis of Cervical Spine Secondary to Tuberculosis

Spondylolisthesis coexisting with tuberculosis is rarely reported. There is a controversy whether spondylolisthesis coexists or precedes tuberculosis. Few cases of pathological spondylolisthesis secondary to tuberculous spondylodiscitis have been reported in the lumbar and lumbosacral spine. All cases in the literature presented as anterolisthesis, except one which presented as posterolisthesis of lumbar spine. Spondylolisthesis in the cervical spine is mainly degenerative and traumatic. Spondylolisthesis due to tuberculosis is not reported in the lower cervical spine. The exact mechanism of such an occurrence of spondylolisthesis with tuberculosis is sparsely reported in the literature and inadequately understood. We report a rare case of high grade pathological posterolisthesis of the lower cervical spine due to tubercular spondylodiscitis in a 67-year-old woman managed surgically with a three-year follow-up period. This case highlights the varied and complex presentation of tuberculosis of the lower cervical spine and gives insight into its pathogenesis, diagnosis, and management.     

A case of testicular rhabdomyosarcoma

Pure testicular rhabdomyosarcoma is a very rare tumor and 7 cases have been reported in literature. A 20-year-old male patient presented with a painless right testicular swelling who underwent inguinal orchiectomy with suspicion of testicular malignancy. The case was regarded as an embryonal rhabdomyosarcoma according to histopathologic and immunohistochemical findings. The case is presented and the relevant literature is reviewed and discussed.     

Osteogenesis imperfecta presenting as simultaneous bilateral tibial tubercle avulsion fractures in a child: a case report

This is a case report of a unique presentation of a mild form of osteogenesis imperfecta (OI) (type IA) in a 9-year-old African-American boy who presented with simultaneous bilateral tibial tubercle avulsion fractures. The boy presented to the authors' emergency room complaining of acute bilateral knee pain. He could not perform a straight leg raise. Other than his orthopaedic examination, significant findings included blue sclera and irregular teeth. Radiographs and magnetic resonance imaging (MRI) confirmed bilateral tibia tubercle avulsion fractures. The patient underwent open reduction and internal fixation of his fractures, and postoperative genetic testing confirmed that the patient was heterozygous for OI. The authors present the fourth reported case of simultaneous bilateral tibial tubercle fractures. To their knowledge this is the first case of OI presenting with these fractures, the youngest reported case, and the first case with MRI documentation.     

Primary non-Hodgkin lymphoma of prostate presenting as benign prostatic hyperplasia

A case of primary non-Hodgkin lymphoma of the prostatic gland is reported. The patient presented with a classic picture of benign prostatic hyperplasia. Review of the literature disclosed about 300 reported cases. Much controversy and confusion exists in the classification of non-Hodgkin lymphoma. The two current classifications are presented, and management of this condition is reviewed.     

An interesting case of aglossia-adactyly syndrome

A case of aglossia-adactyly syndrome with a sagittal band between the floor of the mouth and the palate is reported. The literature concerning this case is briefly reviewed. This case is being presented for its extreme rarity.     

Malignant urothelial tumors in childhood

A case is presented of an adolescent male with a transitional cell tumor in a solitary kidney. This is the first such case reported in the literature. A brief review of epithelial tumors in children is included.     

Primary Extracranial Meningioma of the Maxillary Antrum

A case of primary extracranial meningioma of the maxillary antrum is reported. A 45-year-old male presented with symptoms of chronic sinusitis. Imaging studies showed a soft tissue mass with calcification, filling the maxillary antrum. The mass was removed surgically, and pathological studies revealed a ribroblastic meningioma. The maxillary antrum is an uncommon location of primary extracranial meningioma, and our case is the sixth to be reported in that location.     

48XXYY Klinefelter's syndrome with recurrent foot ulcers: a case report

A case of 48XXYY Klinefelter's syndrome diagnosed with foot ulcers, in a 43-year-old man, is reported. He presented to the Department of Dermatology in our hospital with the chief complaint of recurrent foot ulcers. He was referred to us because of atrophic external genitalia. The present condition and endocrinological examination suggested Klinefelter's syndrome. Chromosomal analysis revealed that his chromosomal type is 48XXYY. This is the 24th case of Klinefelter's syndrome with 48XXYY chromosome and is the 5th case associated with foot ulcers in Japan. Here we report this case together with a brief review of the previously reported cases.     

Primary extracranial meningioma of the maxillary antrum

Imaging studies showed a soft tissue mass with calcification, filling the maxillary antrum. The mass was removed surgically, and pathological studies revealed a ribroblastic meningioma. The maxillary antrum is an uncommon location of primary extracranial meningioma, and our case is the sixth to be reported in that location.     

Silicone lymphadenitis secondary to implant degeneration

The principal objective(s) of this presentation is to report a case of lymphadenitis secondary to implant degeneration. A review of the literature on the history and development of the silicone implant and the durability of the silicone elastomer is presented. A case report with radiologic and histologic documentation is also presented. Silicone lymphadenitis is a rare occurrence and the authors believe they have reported the first case to occur in the lower extremity.     

Primary squamous cell carcinoma of the colon associated with hypercalcemia and hyperleukocytosis. Report of a case

BACKGROUND/AIMS: Squamous cell carcinoma of the colon is a rare entity. We report a case of a patient who presented with a perforated squamous cell carcinoma of the sigmoid colon. RESULTS: A 45-year-old female presented with a 2-month history of worsening abdominal pain, bloody diarrhea, and vomiting. She underwent an exploratory laparotomy and was found to have keratinizing squamous cell carcinoma of the sigmoid colon that had perforated forming multiple abscess cavities. The postoperative course was complicated by hypercalcemia and persistent hyperleukocytosis, ultimately resulting in the patient's death. CONCLUSIONS: We present the second reported case of squamous cell carcinoma of the colon associated with hypercalcemia and the first reported case of associated hyperleukocytosis.     

Lymphangioma of the stomach —Report of a case and review of the literature—

A rare case of a 66 year old man with lymphangioma of the stomach is presented herein. Upper gastrointestinal X-ray series revealed a slow growing submucosal tumor in the anterior wall of the antrum of the stomach which was subsequently found to be lymphangioma after a partial gastrectomy. To our knowledge, this is only the thirteenth case of lymphangioma of the stomach to have been reported in the English literature. A brief review of the English and Japanese literature is presented following the case report.     

Segmental multicystic dysplastic kidney in children

Pediatric segmental multicystic dysplastic kidney is a rare subtype of multicystic dysplastic kidney disease, with only 18 case reports published. All children previously reported with this condition presented during infancy. This is the first case of segmental multicystic dysplastic kidney in an adolescent girl. The case is discussed, along with a review of published reports.     

Chromophobe renal cell carcinoma showing oncocytoma-like hyalinized and edematous stroma: A case report and review of the literature

A case of chromophobe renal cell carcinoma (CRCC) with abundant hyalinized and edematous stroma mimicking oncocytoma is presented. This stromal architecture in the current case has not been reported on CRCC to our knowledge. A further interesting finding is entrapped non-neoplastic tubules in the hyalinized and edematous stroma composing the tumor. These histological features, such as abundant hyalinized and edematous stroma containing non-neoplastic tubules, may be analogous to oncocytoma. We reported a unique case of CRCC and studied with light microscopy and immunohistochemistry.
