Plasma cell granuloma is a tumor-like disease characterized by non-neoplastic polyclonal proliferation of plasma cells and other mononuclear cells. This disease occurs most frequently in the lung and upper respiratory tract, while the involvement of the central nervous system is very rare. A 44-year-old female patient presented with nausea and progressive visual disturbance. Brain magnetic resonance imaging (MRI) revealed the mass along the right tentorium with low signal intensity in the T2 weighted image (T2WI) and fluid-attenuated inversion recovery (FLAIR) sequence, and an isosignal intensity in T1 weighted image (T1WI), the latter of which was enhanced after administration of gadolinium-diethylenetriamine penta-acetic acid (Gd-DTPA). The thickest portion of the tentorium was partially excised via the combined suboccipital and infratentorial approach. The histopathological examination indicated a diagnosis of plasma cell granuloma. Postoperative steroid therapy was administered for remnant tumor control. Although a follow up MRI scan taken 20 months after the operation showed a slight decrease in tumor size, the lesion had extended to the falx and left frontal convexity along with parenchymal edema at 32 months after the operation and the clinical status was aggravated. The mass was removed from the left frontal convexity. Radiation therapy was given, together with steroid administration.

Peripheral giant cell granuloma (PGCG) is an benign non-neoplastic lesion most commonly occurring in oral cavity but extraoral PGCG is extremely rare. Recently, we experienced a case of an isolated PGCG in the parotid gland in 59-year-old man. FNAB findings and radiologic findings including CT and US were suggestive of Warthin's tumor. Partial parotidectomy was performed. Pathologic findings showed fibrillar connective tissue stroma with spindled, ovoid, and round histiocytes-like cells mixed with uneven multinuclear giant cells, small capillaries, hemorrhage, hemosiderin-laden macrophages, and necrosis which were consistent with giant cell granuloma. We report a case of an PGCG in parotid with a review of literature.

Perforating granuloma annulare (PGA), a rare variant of granuloma annulare, is characterized by transepidermal elimination of altered collagen that clinically manifests an umbilicated papule with a central crust. It can be confused with papulonecrotic tuberculid (PNT) because of their similar appearance. Unlike PGA, PNT is usually related to tuberculosis infection with a typical histologic finding of wedgeshaped dermal necrosis. Here, we report the first Korean case of PGA mimicking PNT both clinically and histologically. A 43-year-old Korean woman presented with erythematous papules localized on the extensor surface of her limbs for one year. Some of these papules had a central umbilication or a crust. Regarding comorbidity, she had latent tuberculosis diagnosed with $QuantiFERON^{(R)}-TB$ Gold test about five months ago. She was on antituberculous medication. Initially, a diagnosis of papulonecrotic tuberculid accompanied by latent tuberculosis was considered. However, despite taking the antituberculous medication for five months, her skin lesions were not improved. Biopsy specimen from her arm lesion showed wedge-shaped area of necrosis in the dermis. Additionally, there were multiple focal mucin depositions and palisading granulomatous inflammation throughout the dermis. A diagnosis of PGA was made and she was treated with topical corticosteroid. After two weeks of applying topical corticosteroid, most of her skin lesions disappeared, leaving some hyperpigmented scars.

Thread-lifting is a minimally invasive procedure that shows good results and fewer complications as compared with those results and complications of standard surgery. Many procedures and techniques have been developed to create a younger appearance of facial/neck skin for aging people, and the demand for an improved aesthetic appearance is increasing. Since the incidence of side effects is much less than that of non-absorbable threads, which can lead to complications such as foreign body reactions, polydioxanone (PDO) threads are predominantly used for face lift procedures. A 66-year-old woman presented to our clinic with inflamed palpable masses. She had undergone a face lift with absorbable threads in our clinic 5 months previously. Excisional biopsy was performed with the patient under local anesthesia. During the operation, any threads were not detected and there was both fibrotic scar tissue and granulomatous tissue. For effectively promoting healing and managing the scars, treatment with LDM^®-MED was performed on the day after surgery. The treatment was performed according to the author's protocol. Although foreign body granuloma as a complication after using non-absorbable thread types have been previously reported, it is relatively rare to find this type of complication after using absorbable thread. In this report, we present a case in which a 66-year-old female with foreign body granuloma after undergoing a face lift using absorbable threads was treated with the application of dual-frequency ultrasound, which promoted wound healing.

Pyogenic granuloma is a overzealous proliferation of a vascular type connective tissue as a result of some minor trauma and is a well circumscribed elevated, pedunculated or sessile benign inflammatory lesion of skin and mucous membrane. The clinical features of pyogenic granuloma are indicative but not specific and nearly all cases of pyogenic granulomas are superficial in nature, and there is little if any mention in the literature of these lesions producing alveolar bone even jaw bone loss. This case is somewhat unique in that the lesion was an obvious histologic pyogenic granuloma; however, it appeared to invade the mandibular bone which resulted in the loss of the adjacent teeth. A 12-year-old boy came to Seoul National University Dental Hospital with chief complaints of left facial swelling. The features obtained were as follows; Plain radiograms showed a large well-circumscribed radiolucent lesion on left mandibular ramus area, which made severe expansion of lingual cortex and displacement of lower left 3rd molar tooth germ. Computed tomograms showed large soft tissue mass involving left masticator space with destruction of left mandibular ramus. Histologically, sections revealed loose edematous stroma with intense infiltration of inflammatory cells and proliferation of vascular channels. Also, there were focal areas of extensive capillary proliferation, bone destruction and peripheral new bone formation.

Sarcoidosis, a systemic granulomatous disease of unknown etiology. The presentation of sarcoidal granuloma in neck nodes without typical manifestations of systemic sarcoidosis is difficult to diagnose. We describe the case of a 37-year-old woman with an increasing mass on the right side of neck. The excisional biopsy from the neck mass showed noncaseating epithelioid cell granuloma of the lymph nodes. No evidence of mycobacterial or fungal infection was noted. Thoracic evaluations did not show enlargement of mediastinal lymph nodes or parenchymal abnormalities. Immunohistochemistry showed abundant expression of tumor necrosis factor-${\alpha}$ in the granuloma. However, transforming growth factor-${\beta}$ was not expressed, although interleukin-$1{\beta}$ was focally expressed. These immunohistochemical findings supported characterization of the granuloma and the diagnosis of sarcoidosis. Sarcoidosis can present with cervical lymph node enlargement without mediastinal or lung abnormality. Immunohistochemistry may support the diagnosis of sarcoidosis and characterization of granuloma.

Purpose: Lobular capillary hemangioma is a vascular tumor that commonly occurs as a cutaneous lesion. Intravenous pyogenic granuloma is a rare form of lobular capillary hemangioma that usually occurs in the veins of the neck and the upper extremities. Methods: A 41-year-old man presented with 3 months history of nodules on the left temporal area and these lesions were clinically mistaken for a typical lipoma or epidermal cyst, but the nodules appeared unusually vascular with sentinel veins on excision. Results: On the histopathologic examination, the excised tissue was observed as an intraluminal polypoid mass, which was attached to the vein via a fibrovascular stalk and capillaries in a loose edematous fibromyxoid stroma, and so the lesions were confirmed to be intravenous pyogenic granuloma. At 6 months after excision, there has been no recurrence and the patient is asymptomatic. Conclusion: Intravenous pyogenic granuloma is a rare variant of lobular capillary hemangioma. This article describes the surgical and histopathological findings of treating pyrogenic granuloma.

Artecoll (Artes Medical Inc., San Diego, CA, USA) has recently been developed as a permanent synthetic cosmetic filler. We experienced an inflammatory granuloma resulting from a previous injection of Artecoll at the upper lip, which was regarded as a rare side effect of this filler. A 50-year-old female patient complained of swelling, dull pain, and heat in the right upper nasolabial fold area, which had started one week before her visit to Kyungpook National University Hospital. The patient received topical steroid therapy at a local clinic, which was not effective. At the injection site, a hard nodule was palpated and erythema was observed with mild tenderness. Antibiotic treatment and subsequent incision and drainage did not result in complete cure of the facial swelling, and the facial swelling and pain persisted. Computed tomography showed a lesion approximately 1-cm in size without clear boundaries and relatively increased nodular thickening. Finally, a subdermal lesion was removed via an intraoral vestibular approach. The lesion was diagnosed as inflammatory granuloma by a permanent biopsy. The patient had healed at two months after the filler injection. Although the soft tissue filler is widely used for cosmetic purposes, there is potential for complication, such as the inflammatory granuloma should be considered before treatment.

Histiocytosis-X is a tenn used to define three diseases with similar morphologic characteristics : Letterer-Siwe diseae, Hand-Schuller-Christian disease and Eosinophilic granuloma. In general, they differ in terms of their age of onset, severity of clinical course and site of involvement. Eosinophilic granuloma typically is seen in young adults. Eosinophilic granuloma is diagnosed in the presense of diffuse pulmonary infiltrate, bony involvement. However, the pulmonary radiologic findings of eosinophilic granuloma are variable accordinary to stage of disease. therefore pathologic diagnosis of involving site is essential for confirmative diagnosis of eosinophilic grananuloma. Pathologically. the three disease are characterized by granulomatous infiltration of alveolar septa and bronchial walls and often involvement of bone. The hallmark of this disease is proliferation of the Langerhans' cell. The identifying feature is the X-body or Birbeck granule that is present in Langerhans' cells and histiocytic cells found in the lung of EG patient. We report a case of bilatera1, recurrent and spontaneous pneumothoraces in a 21 year old man with pulmonary histiocytosis-X, which is confirmed by eosinophilc granuloma in bone marrow biopsy and ultrastructural examination in cells obtained from BAL.
