Castleman's disease - hyaline vascular type - clinical, cytological and histological features with review of literature

BACKGROUND AND AIMS Castlemans disease (CD) is a rare disease of lymph node with two identified forms - the hyaline vascular (HV) type or angiofollicular type and plasma cell (PC) type. It usually presents as localized or systemic lymphadenopathy or even as extra nodal mass and may give rise to several differential diagnoses. Fine needle aspiration cytology (FNAC), as the initial investigation, may be misleading. Excision biopsy usually gives the diagnosis. This study analyzes the clinical, cytological and histological features of CD of HV type. MATERIALS AND METHODS All the cases of CD reported between 2001 and March 2008 have been reviewed. Cytology and histopathology slides of all cases were reviewed by two reporting pathologists independently and the clinical records were analyzed. RESULT We had five cases of CD all of which presented as cervical lymphadenopathy of 1 to 5 cms in young patients. Patients were mostly asymptomatic with all relevant investigations within normal limits. The cytology findings mostly showed a predominance of small lymphocytes with capillary fragments. On excision biopsy, all cases were diagnosed as CD of HV type. CONCLUSION CD should be kept as a differential of lymphadenopathy, especially in asymptomatic and young patients.

Value of image-guided fine-needle aspiration cytology—A study of 500 cases

Guided Fine‐Needle Aspiration Cytology (FNAC) as the first line investigation is not only useful in diagnosis of space occupying lesions but can also help in choosing appropriate management. This technique is most useful in diagnosing metastasis but is also helpful in excluding malignancy in some cases. Aim of this study is to analyze the spectrum of cytological diagnosis, adequacy, and clinicoradiological correlation of guided FNAC.

Diffuse vascular malformation of large intestine clinically and radiologically misdiagnosed as ulcerative colitis

Abstract Hemangiomas and vascular malformations of the gastrointestinal tract are rare clinical entities that usually present as overt or occult bleeding. They can be distributed throughout the gastrointestinal system, or present as a singular cavernous hemangioma. Overall, 80% of such malformations are of cavernous subtype and are misdiagnosed as hemorrhoids and ulcerative colitis. Mucosal edema, nodularity and vascular congestion can lead to the incorrect diagnosis of inflammatory bowel disease. We present a case of 26-year-old male who presented with pain abdomen, bleeding per rectum and was treated as a case of ulcerative colitis for past 12 years on the basis of clinical and radiological features. As the patient did not respond, subtotal colectomy was done which on histopathologically reported as cavernous vascular malformation—diffuse infiltrating (expansive type).

Squamous cell carcinoma arising in familial gingival fibromatosis—a rare case report

Abstract Familial gingival fibromatosis is a rare hereditary condition due to chromosomal abnormality which can occur as an isolated disease or as part of a syndrome and has an incidence of 1:350 000. This condition leads to esthetic, functional, psychological and masticatory disturbance of the oral cavity. Here, we present a case of 21-year-old female with severe enlargement of gums in maxilla and mandible. Deciduous teeth were erupted at normal age but the permanent teeth in the oral cavity were not erupted. Her grandmother, father and younger sister were also affected with the same condition. Incisional biopsy from the chronic ulcerated gingiva showed squamous cell carcinoma. Patient was referred to other cancer institution, where metastases to lung, bone and lymph node was detected on CT scan. The diagnosis was made based on clinical examination, family history and histopathological examination.

Warty Carcinoma Penis: An Uncommon Variant

Penile carcinoma frequency varies widely in different parts of the world and comprises 1–10% of all the malignancies in males. Majority of the cases of penile carcinoma are squamous cell carcinoma of penis comprising 60% to 70% of all cases. Warty carcinoma of penis is an unusual neoplasm and a variant of penile squamous cell carcinoma comprising 5%–10% of all the variants. The other histological variants include basaloid, verrucous, papillary, sarcomatous, mixed, and adenosquamous carcinoma. The various histological entities with an exophytic papillary lesions including warty carcinoma are together referred to as the “verruciform” group of neoplasms. The warty carcinoma has to be differentiated from these lesions and is typically distinguished by histological features of hyperkeratosis, arborescent papillomatosis, acanthosis, and prominent koilocytosis with nuclear pleomorphism. We present a case of 65-year-old male with growth measuring 6 × 4 cm in the penis who underwent total penectomy and was diagnosed as warty carcinoma penis.
