Diff-Quik cytologic recognition of Chlamydophila psittaci in orolabial lesions of Stevens-Johnson Syndrome.

Background: Chlamydophila psittaci causes psittacosis, an ornithosis acquired usually from infected birds. The disease is often focal and pneumonic but on rare instances can be protean and fatal. Diagnosis is by Chlamydophila serology, which may take as long as 21 days or more.

Herpes simplex virus type-1 pneumonitis in immunocompetent young woman.

A healthy young woman presented with an overwhelming hyperacute herpes simplex virus-1 pneumonia that dramatically responded to intravenous acyclovir. It is postulated that the infection was a reactivation of latent virus in the vagal ganglia, in the absence of retrograde extension of herpes labialis/gingivostomatitis, or hematogenous spread from extragenital and other sources of infection. It is also postulated that the patient's amazing improvement overnight was a real-time coincidence of spontaneous recovery from the viral infection and prompt initiation of acyclovir treatment.

The role of fine needle aspiration cytology in medical-surgical missions.

Objective: To relate a 6-year, short-term experience of utilizing fine needle aspiration cytology (FNAC) during medical-surgical missions in the impoverished areas of the Philippines.

Study Design: FNAC is a simple, accurate, fast and economical procedure and requires the simplest devices to implement. During medical-surgical missions to the poorest areas in the Third World countries, where there is almost complete lack of tissue processing and frozen section evaluation, and scarcity of laboratory testing, FNAC becomes a practical technique to use.

Clear cell hidradenocarcinoma developing in pacemaker pocket.

An octagenerian woman developed clear cell hidradenocarcinoma, a rare neoplasm of eccrine sweat gland origin, 4 years following pacemaker implantation in her right lateral chest. The tumor immunohistochemically mimicked a metastatic lobular breast carcinoma, for example, strongly positive estrogen, weakly positive progesterone, and weakly reactive mammoglobin. A complete surgical excision of the tumor was complemented with ipsilateral dissection of involved adjacent axillary lymph nodes.

Cutaneous tumefaction in empyema necessitatis.

Background: Empyema necessitatis refers to a collection of exudative fluid that extends directly from the pleural cavity to the thoracic wall to form a mass in the extrapleural soft tissue of the chest. It was an uncommon complication of tuberculous pleural effusion even in the pre-antibiotic era, and has also been associated with bacterial lung abscess, actinomycosis, blastomycosis, and malignancies.

Methods: Seven instances of chest wall mass lesion secondary to empyema necessitatis, diagnosed by fine-needle aspiration biopsy (FNAB), are reported.

Sebaceous lymphadenoma identified by fine needle aspiration biopsy: a case report.

Background: Sebaceous lymphadenoma of the parotid gland is a rare benign neoplasm. This is the first reported case of fine needle aspiration biopsy (FNAB) findings for sebaceous lymphadenoma of the parotid gland.

Case: A 60-year-old male presented with painless, bilateral parotid swelling noted for 5 months.

Parotid abscess due to salmonella enteritidis: A case report.

Background: Salmonella infection of the parotid gland is rare.

Case: An instance in a 50-year-old man of Salmonella enteritidis parotiditis initially recognized by microbial culture of a fine needle aspiration cytology material is described. The identified predisposing factor was chronic alcoholic abuse.

HIV and HHV-8 negative primary effusion lymphoma in a patient with hepatitis C virus-related liver cirrhosis.

Primary effusion lymphoma (PEL) or body cavity-based lymphoma (BCBL) is a unique subgroup of B-cell lymphomas that exhibits exclusive or dominant involvement of serous body cavities without a detectable tumor mass. We present a case of a PEL/BCBL that exclusively involved the peritoneal cavity of a 58-year-old immunocompetent male with hepatitis C virus (HCV)-related liver cirrhosis. The lymphoma cells were large, highly atypical and expressed CD19, CD20, CD22, CD10, HLA-DR, and CD45 with kappa light chain restriction.

Aneurysm of the dorsalis pedis artery -- a case report.

Aneurysms of the pedal arteries are uncommon; however, they can be identified upon clinical exam and confirmed by angiogram and color-flow duplex scan. Surgical treatment options include ligation or primary repair. The authors present a case of an aneurysm of the dorsalis pedis artery in a diabetic patient.
