Hydatid disease is a parasitic infestation caused by the larval form of the cestode worm Echinococcus. The most commonly encountered form of the disease is visceral hydatid cyst caused by Echinococcus granulosus or dog tapeworm. We hereby represent an unusual case of hydatid disease located in the neck region in a 22-year-old female patient.

BACKGROUNDThe dermoscopic criteria of extrafacial melanomas are well-known.OBJECTIVETo determine the frequency of dermatoscopic findings in head and neck melanomas (HNM) and to assess the distinguishing dermoscopic criteria of facial and extrafacial melanoma.METHODSThis observational study included 108 patients with HNM (63% male, mean age 64 years). Participants underwent individual dermoscopic imaging of clinically melanoma. All lesions were excised, and histopathological examination was performed on all specimens.RESULTSDrawing on histopathological analysis, lentigo maligna melanoma or lentigo maligna was diagnosed in 60 lesions, superficial spreading melanoma in 18, nodular in 10, desmoplastic in 8, superficial spreading melanoma in situ in 12. The most frequent location for head and neck melanoma was the cheek (60 patients, 55.6%). Eight prominent dermatoscopic features were observed in facial melanoma: annular-granular pattern (18%); rhomboidal structures (29%); pseudonetwork (29%); asymmetrical, pigmented, follicular openings (51%); obliterated hair follicles (8%); red rhomboidal structures (18%); increased density of the vascular network (32%); scar-like depigmentation (59%).CONCLUSIONSHNM has specific dermoscopic features, and classical extrafacial dermoscopic rules are less useful for diagnosis of facial melanoma. In our study, further characteristic dermatoscopic findings were detected in facial melanoma such as low frequencies of irregular dots, 2 or fewer colors in lesions, the presence of pseudonetwork, increased density of the vascular network, red rhomboidal structures, in addition to dermatoscopic findings of extrafacial melanoma. Thus, it is concluded that the prediction and identification of HNM may be evident with the help of these signs.

Giant cell granulomas account for 7% of all benign tumors of the jaw. They are commonly seen as asymptomatic masses. A 4-year-old boy with an exophitic, crusty, hemorrhagic mass on the anterolateral region of the right maxilla was referred to our department. Pathological examination was reported as giant cell granuloma. A mixture of prednisolone, lidocaine and adrenaline was injected intralesionally once a week and oral fluocortone was added to this therapy. A limited surgery could be performed. Intralesional prednisolone and systemic fluocortone therapy seems to be effective, as the lesion stopped growing and increase in bony structures was observed radiologically.

Metastatic lymph node involvement localized to the auricular, infra-auricular, and postauricular was present in the pathological specimens of all patients with lesions who had selective neck dissection I to IV included into their treatment. The depth of invasion of SCCs was found to be statistically significant in terms of recurrences.

ÖZETCastleman hastalığı (CH), en sık mediastende asemptomatik kitle olarak görülen lenfoproliferatif bir hastalıktır. Baş boyun bölgesinde ise en sık boyun da görülür. Oral kavite de yerleşimi nadirdir. Tedavisinde cerrahi eksizyon uygulanır. Bu makalede sağ ve sol yanak mukoza altında, giderek büyüyen şişlik şikayeti ile tarafımıza başvuran ve histopatolojik tanısı castleman hastalığı-plazma hücreli tip olarak raporlanan, non hodgkin lenfoma (NHL) öyküsü olan hasta, literatür eşliğinde sunulmuştur. Anahtar Kelimeler: Bukkal Mukoza, Castleman Hastalığı, Non hodgkin lenfoma ABSTRACT Castleman disease (CD) is a lymphoproliferative disorder that is most frequently seen as an asymptomatic mass in the mediastinum. Among the head and neck region, the neck is the most frequent localization. It is seldom localized in the oral cavity. Surgical excision is the primary choice of treatment. The current study presents a patient with previous non-Hodgkin Lymphoma (NHL) history, who was complaining of a mass gradually increasing in size beneath the right and left buccal mucosa and a histopathological diagnosis of Castleman disease -plasma cell type. The related literature is also reviewed.
