Eccrine Porocarcinoma of the Eyelid Treated With Mohs Micrographic Surgery

DERMATOLOGIC SURGERY, Issue 4 2004
Renee A. D'Ambrosia BS
Background. Eccrine porocarcinoma (EPC) is a rare malignant tumor of the eccrine sweat glands. The lesions are reported to occur most commonly on the lower extremity with variable prognosis. Objective. To discuss the clinical and histologic features and the prognosis of EPC. Methods. We report a 71-year-old man who presented with an asymptomatic lesion on his lower eyelid that had been present for 6 weeks. Results. The 4×4-mm lesion was removed in two stages using the Mohs micrographic surgery fresh-tissue technique. The histopathologic diagnosis was primary EPC. Conclusion. EPCs most commonly occur on the lower extremity. This case is interesting because the lesion was located on the lower eyelid. [source]

Pediatric primary cutaneous marginal zone lymphoma: in association with chronic antihistamine use

JOURNAL OF CUTANEOUS PATHOLOGY, Issue 2006
Novie Sroa
There have been no prior reports of this lymphoma occurring in American children. We present a case of a 15-year-old male with a history of atopic diathesis and chronic use of antihistamine agents who presented with an asymptomatic lesion on his left forearm of 6 months duration. Because histopathological and immunohistochemical studies were compatible with marginal zone lymphoma, and the patient had no associated extracutaneous disease, the diagnosis of primary cutaneous marginal zone lymphoma was rendered. Based on the patient's past medical history prior to appearance of lesion, it was postulated that the development of lymphoma was associated with the ingestion of antihistamines and further propagated by his underlying atopic diathesis.

Benign parathyroid cyst causing vocal fold paralysis: A case report and review of the literature

HEAD & NECK: JOURNAL FOR THE SCIENCES & SPECIALTIES OF THE HEAD AND NECK, Issue 6 2006
Daniel H. Coelho MD
Abstract Background. Parathyroid cysts are uncommon, frequently asymptomatic lesions of the neck and superior mediastinum. Symptomatic parathyroid cysts are very rare, with roughly only 200 cases reported in the literature. Of these, only nine cases have been reported with recurrent laryngeal nerve (RLN) paralysis Methods. We report a case of a 49-year-old man initially seen with a 6-month history of worsening hoarseness. Physical examination revealed a palpable 3-cm, firm, smooth, nontender mass of the right thyroid lobe. Fiberoscopic laryngoscopy showed right vocal cord immobility consistent with RLN paralysis. After CT and fine-needle aspiration of the mass, the patient underwent a right thyroid lobectomy. During surgery, the recurrent laryngeal nerve was found to be stretched and adherent to a right inferior lobe mass. Results. Histologic analysis of the surgical specimen revealed a benign parathyroid adenomatous cyst. Postoperatively, the patient's voice improved markedly. This case represents an extremely rare return of function of the RLN after cyst removal. Conclusion. Parathyroid cysts should be included in the differential diagnosis for vocal fold paralysis. © 2006 Wiley Periodicals, Inc. Head Neck 28:564,566, 2006 [source]

Interleukin-6 and granulocyte-macrophage colony-stimulating factor in apical periodontitis: correlation with clinical and histologic findings of the involved teeth

MOLECULAR ORAL MICROBIOLOGY, Issue 1 2003
T. Radics
Apical periodontitis is characterized by the presence of immunocompetent cells producing a wide variety of inflammatory mediators. Releasing cytokines with long-range action, such as interleukin-6 (IL-6) and granulocyte-macrophage colony-stimulating factor (GM-CSF), apical periodontitis may induce changes in remote organs of the host. This study quantified the levels of IL-6 and GM-CSF in symptomatic and asymptomatic human periradicular lesions. Lesions were also characterized by size and histologic findings. Tissue samples were homogenized and supernatants were assayed using an enzyme-linked immunosorbent assay (ELISA). Correlations between cytokine levels and characteristic features (as single variables) of the lesions were analysed. There was a trend for higher levels of IL-6 and GM-CSF in symptomatic than in asymptomatic lesions, but the difference was not significant. Levels also tended to be higher in large than in small lesions, in polymorphonuclear (PMN) cell-rich than in PMN cell-poor samples, and in epithelialized than in non-epithelialized lesions. Significantly higher levels of IL-6 (778.1 ± 220.5 pg/,g) and GM-CSF (363.3 ± 98.4 pg/,g) were found in samples coincidentally possessing symptomatic and epithelialized features than in asymptomatic, small, PMN cell-poor, non-epithelialized lesions (IL-6: 45.2 ± 13.1 pg/,g and GM-CSF: 135.1 ± 26.4 pg/,g). These results suggest that symptomatic lesions containing epithelial cells represent an immunologically active stage of apical periodontitis, whereas asymptomatic, small, PMN cell-poor, non-epithelialized lesions represent healing apical lesions.

Blue Nevi of the Sinonasal Mucosa: A Report of Two Cases and Review of the Literature,

THE LARYNGOSCOPE, Issue 2 2007
Wen-Yu Chuang MD
Abstract Blue nevi are uncommon melanocytic proliferations. They occur mostly in the skin and occasionally in mucosae. Blue nevi of the sinonasal mucosa are extremely rare with only two cases reported to date. We report two more cases and review the literature. Compared with sinonasal malignant melanomas, which usually present as symptomatic tumors, sinonasal blue nevi are asymptomatic lesions found incidentally. A biopsy is required for a definitive diagnosis. Although none of the four cases had recurrence, given a rare but possible occurrence of malignant transformation in cutaneous blue nevi, complete excision with follow up should be the treatment of choice.
