Abstract
BACKGROUND Pancreatic panniculitis is a rare form of panniculitis generally associated with acute or chronic pancreatitis, and less frequently with pancreatic carcinoma. Clinically, it presents with subcutaneous nodules usually located in the lower extremities, however, it presents an almost pathognomonic histopathological finding with enzymatic fat necrosis in the adipose tissue. METHODS In this retrospective case series of five hospitals, biopsy specimens of cutaneous lesions of pancreatic panniculitis were reviewed. Clinical information was obtained through medical records. RESULTS A total of 34 cases were included, 23 women and 11 men, aged between 31 and 92 years. The most common associated pancreatic disease was acute pancreatitis (23 cases) and its main triggering cause was gallstones (17 cases). In two patients it was related to chronic pancreatitis and six cases were associated with malignancy. Histopathological findings were always the key to diagnosis. In the biopsies reviewed, mostly lobular panniculitis with the characteristic necrosis of the adipocytes was observed. In addition, nine of the cases presented with Splendore-Hoeppli phenomenon. CONCLUSIONS We present the largest series of pancreatic panniculitis. Clinically, the female predominance and biliary lithiasis as the main cause of acute pancreatitis are to be emphasized. Histopathologically, a peripheral eosinophilic striated rim surrounding aggregates of ghost adipocytes consistent with Splendore-Hoeppli is an additional clue to its diagnosis.

Abstract
Pilomatrixoma (PMX), also known as calcifying epithelioma of Malherbe, is a rare benign neoplasm that arises from the hair matrix cells, commonly in the head, neck, and upper trunk regions, infrequently affecting upper and lower extremities. It has to two peaks of presentation: under 20 years of age or between 50 and 65 years of age, slightly more common in females. The neoplasm exhibits diverse clinical manifestations and is frequently subject to misdiagnosis with alternative dermatological diseases. We present an atypical case of PMX affecting the upper extremity of a 62-year-old female patient. Surgical removal of the affected tissue under local anesthesia was performed, and subsequent histopathological analysis confirmed the presence of PMX. Based on the literature search we performed, we found out that this pathology is underreported in Jordan, with only one study published describing this tumor in the maxillofacial region. Physicians should be aware of this condition and its different presentations to include it in the differential diagnosis of suspected cases to provide the appropriate management and follow-up.

Abstract
Pancreatitis, panniculitis, and polyarthralgia (PPP) syndrome is a rare complication of chronic pancreatitis and occurs due to leakage of pancreatic enzymes in the systemic vasculature. This enzyme leakage leads to multiple manifestations such as polyarthralgia, panniculitis, and bone necrosis due to tissue autodigestion.The inciting pancreatic pathology may be masked, and the presentation may be due to one of the systemic consequences of enzyme leakage, which can present as a diagnostic challenge for clinicians. Here we present a patient who presented with nodular lesions and bone necrosis, and was found to have PPP syndrome. Therefore, a proper understanding of pathophysiology and radiology findings can help with prompt diagnosis and early exploration of management options.

Abstract
BACKGROUND Pilomatricoma is a benign tumour that originates in the outer sheath of the hair follicle root. The clinical diagnosis of this rare entity is often missed, possibly due to a lack of awareness. Its characteristic cytomorphological features are sheets of ghost cells, basaloid cells, calcification and foreign body giant cell reaction. However, the above features may not all be present in all cases, rendering cytological diagnosis difficult. MATERIALS AND METHODS This retrospective study included all cases of pilomatricoma diagnosed on fine needle aspiration over a period of 4 years. The histopathological diagnosis was retrieved for the cases wherever possible. A detailed histopathological and cytological evaluation was performed for the various components-basaloid cells, ghost cells, calcified debris, foreign body giant cells, bare nuclei, neutrophils, and macrophages-and they were graded on a scale of 0 to 3+. RESULTS The 28 cases included 8 female and 20 male patients with a mean age of 34.6 years. Most cases (22 cases; 78.6%) were located in the head and neck, with the scalp being the most common site. Twenty-five cases were cytologically diagnosed as pilomatricoma based on a variable admixture of the various components-nests of basaloid cells, ghost cells, foreign body giant cell reaction, calcified debris and viable squamous cells. However, in two cases which showed an absence of basaloid cells, a differential diagnosis of epidermal inclusion cyst was also included. Another case showed a predominance of basaloid cells with a paucity of ghost cells, so a differential diagnosis of adnexal tumour was also included. Among all the cytological parameters, sheets of ghost cells followed by nests of basaloid cells and foreign body giant cell reaction had the highest sensitivity in the cytological diagnosis of pilomatricoma. CONCLUSION The presence of sheets of ghost cells is the most sensitive parameter for the cytological diagnosis of pilomatricoma. It is important that pilomatricoma should be considered in the differential diagnosis of subcutaneous masses, particularly in the head and neck region.

Abstract
Nanoparticles (NPs) designed for various theranostic purposes have hugely impacted scientific research in the field of biomedicine, bringing forth hopes of a future revolutionized area called nanomedicine. A budding advancement in this area is the conjugation of various cell membranes onto nanoparticles to develop biomimetic cells called 'Nanodecoys' (NDs), which can imitate the functioning of natural cells. This technology of coating cell membranes on NPs has enhanced the working capabilities of nano-based techniques by initiating effective navigation within the bodily system. Due to the presence of multiple functional moieties, nanoparticles coated with cell membranes hold the ability to interact with complex biological microenvironments inside the body with ease. Although developed with the initial motive to increase the time of circulation in the bloodstream and stability by coating membranes of red blood cells, it has further outstretched a wide range of cell lines, such as mesenchymal stem cells, beta cells, thrombocytes, white blood cells, and cancer cells. Thus, these cells and the versatile properties they bring along with them open up a brand-new domain in the biomedical industry where different formulations of nanoparticles can be used in appropriate dosages to treat a plethora of diseases. This review comprises recent investigations of nanodecoys in biomedical applications.

Abstract
There are a number of benign tumors of the nose and pharynx that are seldomly reported in literature but that can sometimes prove difficult to treat and extremely important for differential diagnosis. The present study presents cases of rare benign tumors localized in the pharynx, nasal and sinus cavities, as well as reviews of literature and historical references for each type of tumor. Unilateral nasal hemangioma in a 72-year-old male which, although not a rare pathology, raised problems due to auto-resection of the tumor. The surgeon was able to pull it out with ease without bleeding; it is possible that the mass would have eventually fallen out. Pilomatrixoma is a relatively uncommon ectodermal benign tumor of the skin derived from hair matrix cells. Surgical resection is curative but recurrence is possible (≤5% risk). The presented case is of a 26-year-old female with a pilomatrixoma of the left cheek who, for aesthetic reasons, refused a classical external surgical approach. Trans-oral resection was performed, which proved feasible but laborious and prone to recurrence. Inverted Schneiderian papilloma is a rare benign tumor of the nasal and sinus cavities with increased potential for invasion, recurrence and malignant transformation compared with other types of papilloma and other benign tumors of the area. The tumor represents 0.5-4.0% of all nasal tumors and has been described under different names, such as villiform cancer and cylindrical/transitional papilloma. The present study reports a rare case of bilateral papilloma in a 68-year-old male. He presented with bilateral evolving nasal obstruction and hyposmia. Following surgery, the patient was treated by a multidisciplinary team and followed by a respiratory rehabilitation program.

Abstract
BACKGROUND Ghost cells (GCs) are cells with distinct intracytoplasmic keratinization, which leads to the preservation of the cellular outline with a clear area corresponding to the previous nucleus location. GCs may show various patterns, such as degeneration, tissue granulation, and calcification. Their true nature and the mechanism regulating the conversion of odontogenic epithelial cells into GCs remain unclear. GC keratinization is different from normal keratinization as they are larger than keratotic squames, are frequently vacuolated, and have prominent nuclear membrane remnants. Few cystic lesions, odontogenic tumors, and non-odontogenic tumors, such as calcifying odontogenic cyst, craniopharyngioma, pilomatrixoma, odontoma, dentinogenic ghost cell tumor, and ghost cell odontogenic carcinoma, exhibit GCs as a typical feature. The Wnt and Notch signaling pathways play a role in the histogenesis of the neoplasms. HIGHLIGHT The review clarifies the various proposed hypotheses of the histogenesis of GCs, including molecular pathogenesis. Diagnostic workup for the identification of GCs, including special staining and immunohistochemistry, has been extensively discussed. A stepwise algorithm for identifying odontogenic and non-odontogenic lesions containing GCs has been proposed. Additionally, the prognostic role of GCs in the lesions has been elucidated. CONCLUSION Among the various hypotheses of the origin of GCs, we suggest that aberrant keratinization is the most accepted based on various immunohistochemical studies and special staining characteristics. GCs are a distinct characteristic entity of many odontogenic and non-odontogenic lesions; however, it remains controversial whether their presence has any pathognomonic role in the biological nature of these lesions.

Abstract
We report a rare case of dentinogenic ghost cell tumor (DGCT) associated with complex composite odontoma in a 17 years male affecting the posterior segment of the mandible. On radiographic examination, there was a well-defined multilocular radiolucency surrounding the radio opaque mass with respect to 44, 45 and 46. Histopathologically it showed ameloblastomatous proliferation with dentin like areas and ghost cells. It was associated with tooth like structures consisting of dentin, cementum and pulp like areas. DGCT with odontoma is extremely rare with only two cases being reported in literature till date. The management with its rare occurrence is discussed here.

Abstract
The aim of this clinical report is to document a rare and unusual case of calcifying odontogenic cyst (COC) in the maxillary anterior region in a 13-year-old girl. A COC is an extremely uncommon developmental, odontogenic entity and accounts for 0.3%–0.8% of odontogenic cysts. The lesion presents as an array of varied radiographic and clinicopathological characteristics and biological attributes and exists in three histomorphologic patterns – benign cystic, solid (neoplastic) and aggressive (malignant) forms. Thus, several nomenclatures and classifications have been put forth to explain the nature of the clinical entity. However, ambiguities regarding the exact nature of the lesion still prevail. Due to nonspecific clinicoradiographic features, histopathological interpretation remains the key for diagnosis. We report an uncommon occurrence of COC in a 13-year-old female who reported to our Outpatient Department with an asymptomatic right midfacial swelling. The clinical and radiographic findings were suggestive of adenomatoid odontogenic tumor and dentigerous cyst. The decision to enucleate the lesion was considered, and histopathological features were compatible with the diagnosis of COC. Re-ossification with no recurrence was noticed after a 1-year follow-up. COC is an unusual developmental odontogenic cyst that clinically and radiologically simulates other more common jaw entities. Thorough knowledge of the bizarre presentation and biological attributes of such lesions are imperative for an early diagnosis and definitive treatment. Long-term follow-up is advocated to prevent recurrences.

Abstract
Dentinogenic ghost cell tumor (DGCT) is a rare benign tumorous form of calcifying odontogenic cyst (COC) characterized by the presence of ghost cells but it seems to have more aggressive behavior. It represents 11.5% of COCs. In this work, we report a case of a 60-year-old male patient with DGCT in the posterior region of the right mandible treated with surgical enucleation.

Abstract
A 24-year-old male reported to the outpatient department with a complaint of swelling of the anterior lower jaw region for 9 months with history of traumatic injury and extraction of teeth from the same region, a month before the onset of swelling. Swelling was obvious extra- and intraorally which on examination presented as a soft to firm non-tender and non-fluctuant mass with an approximate size of 4 cm × 3 cm, extending from 34 to 43 region with obliteration of labial vestibule. Panoramic radiograph and cone-beam computed tomography showed a well-defined radiolucency in the mandibular anterior region crossing the midline with erosion of labial bony plates and root of 42 along with a tooth-like radiopaque mass within the lesion. Provisional diagnoses of odontogenic keratocyst, ameloblastomas, central giant cell granuloma and calcifying epithelial odontogenic tumor were listed. The histopathological and immunohistochemical examination of lesion followed by the biopsy confirmed the diagnosis of Ghost cell odontogenic carcinoma.

Abstract
The aim of this work is to establish a large volume batch production system to produce sufficient volumes of ghost cells to facilitate hemolysis testing of mechanical circulatory support devices. A volume of more than 405 mL with a hematocrit of at least 28% is required to perform in vitro hemolysis testing of mechanical circulatory support devices according to international standards. The established ghost cell production method performed at the institute is limited to 3.1 mL of concentrated cells, that is, cells with 100% hematocrit, due to predominantly manual process steps. Through semi-automation of the existing method by using the large volume batch production system, productivity is increased 60-fold to 188 mL while almost doubling process efficiency to 23.5%. Time-consuming manual work such as pipetting is now supported by sensor-based process engineering. With the help of the large volume batch production system, the objective of producing large quantities of ghost cells is successfully achieved. Thus, this work lays the foundation for spatially resolved hemolysis evaluation of mechanical circulatory support devices in combination with the small-scale fluorescent hemolysis detection method.

Abstract
Ghost cell odontogenic carcinoma (GCOC) is a malignant odontogenic epithelial tumor which is an exceedingly rare, highly aggressive, rapidly growing, and infiltrative tumor forming the malignant counterpart of long-standing benign cystic lesions coming in the spectrum of calcifying odontogenic cysts. To date, only a few cases have been reported in the medical literature. A case of unusual presentation of GCOC is presented and the clinical, histopathological, and immunohistochemical features are discussed along with a literature review. Our case report further emphasizes the bizarre biological behavior of this tumor and the need for strict long-term surveillance of the patients as metastasis to distant sites has been reported.

Abstract
Calcifying odontogenic cyst (COC) is a rare odontogenic cyst with ameloblastic epithelial lining containing clusters of ghost cells. COCs have been described in association with several odontogenic tumors, more commonly odontomas and rarely with dentigerous cyst (DC). In this article, we describe a case of COC associated with DC in a 15-year-old girl, who presented with a swelling on the right middle third of the face, producing facial asymmetry. Panoramic radiography showed a well-circumscribed, corticated, and unilocular radiolucency at the level of the right maxillary sinus, involving 2 unerupted premolars. The lesion was enucleated and histologically revealed a COC associated with DC, which presented mucous metaplasia. Immunohistochemical reactions were performed to better illustrate this rare synchronous occurrence of COC and DC, showing positivity for CK5, CK14, CK19, and p63 in both lesions. CK18 was negative in COC, and Bcl-2 was negative in DC. Periodic acid Schiff highlighted the mucous cells in the DC lining.

Abstract
Ghost cell odontogenic carcinoma (GCOC) is a rare malignant neoplasm characterized by the presence of ghost cells. It is considered to arise either de novo or from a preexisting benign precursor, calcifying odontogenic cyst (COC), or dentinogenic ghost cell tumor (DGCT). We report a case of a 44-year-old Japanese male with a left maxillary tumor. The patient received treatment to resect the left maxillary cyst 25 years prior; however, the details were uncertain. The tumor was resected with clear margins. Taken together with the results of histological and immunohistochemical examinations, the tumor was categorized between GCOC and DGCT, and we diagnosed the tumor as GCOC suggesting similarity to DGCT. Further, we focused on CTNNB1, which encodes β-catenin and is frequently mutated in COCs. In this tumor, we identified CTNNB1 Ser33Cys, one of the mutations typically found in COCs. This finding suggests that CTNNB1 is a common target for the pathogenesis of tumors accompanied by ghost cells.

Abstract
Dentinogenic ghost cell tumor (DGCT) is a rare, odontogenic neoplasm which is considered to be a solid variant of calcifying odontogenic cyst (COC) with locally aggressive behavior. It accounts for only 2–14% of all COCs. To the best of our knowledge, only 88 cases of DGCT have been reported in the literature from 1968 to 2014. Herewith, we report a case of DGCT in a 68-year-old male patient with clinical presentation as a soft tissue growth over alveolar ridge and histopathologically characterized by ameloblastomatous epithelium, abundance of eosinophilic material and ghost cells.

Abstract
BACKGROUND Pilomatrixoma, craniopharyngioma, and calcifying cystic odontogenic tumor are the main entities presenting ghost cells as an important histological feature, in spite their quite different clinical presentation; it seems that they share a common pathway in the formation of these cells. The aim of this study is to examine and compare the characteristics of ghost and other cells that form these lesions. METHODS Forty-three cases including 21 pilomatrixomas, 14 craniopharyngiomas, and eight calcifying cystic odontogenic tumors were evaluated by immunohistochemistry for cytokeratins, CD138, β-catenin, D2-40, Glut-1, FAS, CD10 and also by scanning electron microscopy. RESULTS The CKs, CD138, β-catenin, Glut-1, FAS, and CD10 were more often expressed by transitional cells of craniopharyngioma and calcifying cystic odontogenic tumor, compared with pilomatrixoma. Basaloid cells of pilomatrixoma showed strong positivity for CD138 and CD10. Differences on expression pattern were identified in transitional and basal cells, as ghost cells were negative for most antibodies used, except by low expression for cytokeratins. By scanning electron microscopy, the morphology of ghost cells were similar in their fibrillar cytoplasm, but their pattern varied from sheets in pilomatrixoma to small clusters in craniopharyngioma and calcifying cystic odontogenic tumor. CONCLUSIONS Mechanisms involved in formation of ghost cells are unknown, but probably they follow different pathways as protein expression in the basal/transitional cells was not uniform in the three tumors studied.

Abstract
Ameloblastomas are regarded as a homogeneous group of neoplasms with locally invasive character. They generally do not show induction of dental hard tissue formation except in few cases. Biological behavior and histogenesis of these tumors is still unexplored as there is lack of relevant studies and long follow-up of these patients. So, we aimed to report this rare case of dentinoameloblastoma with unique presence of ghost cells in middle-aged female involving maxilla with emphasis on its biological behavior. We conclude that although histogenesis of this tumor is not clear but biological potential is similar to conventional ameloblastoma requiring wider excision.

Abstract
The calcifying odontogenic cyst was first reported by Gorlin et al. in 1962. It had been classified as a neoplasm related to the odontogenic apparatus because of its histological complexity and morphological diversity until it was renamed as a calcifying cystic odontogenic tumor by the WHO, in 2005. Here we describe a case of mandibular calcifying cystic odontogenic tumor in a 75-year-old male, which was present since five years, with a history of occurrence after the extraction of teeth in the involved region. The lesion was surgically removed and a histopathological examination revealed a cystic tumor with predominance of ghost cells and some amount of dentinoid tissue.

Abstract
Calcifying odontogenic cyst (COC) is an uncommon benign cystic neoplasm of odontogenic origin, which shows extensive diversity in its clinico-pathological appearances and biological behavior. It most commonly occurs in broader age group of 1-82 years in anterior part of jaws which is classically described by presence of ghost cells. There are variants of COC according to clinical, histopathological, and radiological characteristics. Therefore a proper categorization of the cases is needed for better understanding of the pathogenesis of each variant. Here we report a rare case of ameloblastomatous calcifying ghost cell odontogenic cyst in 24 year old female with brief review of literature. Presence of ameloblastomatous proliferation and impacted canine presented a diagnostic dilemma and was diagnosed by careful radiographic and histopathogical interpretation. Long follow up and more case report are required to shed light on its behaviour as there scarcity of data of this lesion in literature.
